A worldwide pandemic is throwing curve balls at the competition with hubs, restrictions on personal lives and floating fixtures.

Here we look at how your team is travelling after four rounds.

For: Chayce Jones' performance against Brisbane is giving Crows' fans something to cling on to in an otherwise bleak start to the season. The former top-10 draft pick is clever around the stoppages, has goal nous and pace. One to watch. Sent an injury scare through the team on Wednesday.

Against: Scoring is proving a problem with the Crows averaging a paltry 45 points across their first four games. Defensively they're also struggling, conceding 87 points on average in shortened games.

For: The motorbike is revving up with goal sneak Charlie Cameron building on his 2019 All-Australian form. Has kicked nine goals in four matches with his pace, energy and marking ability ensuring every Lions' forward 50 entry sends a scare through opposition back lines.

Against: A lower leg injury to captain Dayne Zorko robs the Lions of experience and creativity in the midfield. A multiple club best-and-fairest winner who can hit the scoreboard. Luckily for coach Chris Fagan he has Lachie Neale and Hugh McCluggage to fill the void.

For: Jacob Weitering is delivering as a former number one draft pick and is now one of the best key defenders. Rarely beaten one-on-one and looks comfortable in his own skin after overcoming a shaky period during the Blues' dark days.

Against: The Blues could be 4-0 if not for lapses. Were poor early against Richmond in round one before flying home and clawed back at 42-point deficit against Melbourne only to fall a point short.

For: Boasts class on every line but the development of brothers Callum and Tyler Brown has been a bonus. Not over-awed, they're slowly establishing themselves as best 22 regulars.

Against: A serious knee injury to the high-flying Jeremy Howe robs the Pies' defence of one of its most reliable assets. Howe is dynamic in the air and strong one-on-one.

For: Former number one draft pick Andrew McGrath has transitioned from the half-back flank to midfield with ease, complementing Zach Merrett in the middle. He is averaging a career-high 22 disposals.

Against: The Bombers found themselves in a PR battle when Irishman Conor McKenna sent a COVID-19 scare through their camp. It forced a match against Melbourne to be postponed.

For: The athletic Griffin Logue is holding down the fort in an undermanned defence missing reliable key backs Alex Pearce and Joel Hamling. Boasts the strength to play on tall opponents and the ability and pace to negate pesky small forwards.

Against: Honourable losses only get a team so far. Have lost three matches by under 13 points and another by 29 - to ladder-leader Port Adelaide. Need to wipe out lapses if they're to secure Justin Longmuir's first win as coach soon.

For: Brandan Parfitt is emerging as a young midfielder who can complement the experienced Joel Selwood and Patrick Dangerfield. Uses the ball well and hits the scoreboard.

Against: Slow, methodical play is frustrating Cat supporters while the ruck remains a bugbear. Do they need to trade a top-liner in or go to the draft?

For: Matt Rowell. What more needs to be said? Three perfect 10 scores in the AFL Coaches Association in a row and talk of becoming a first-year Brownlow Medallist.

Against: A club which was lacking relevance is suddenly everyone's second favourite team with its daring playing style but we're yet to see former top-three pick Izak Rankine due to injury.

For: The Giants have found another gem in Tom Green. The teenager showed composure beyond his years, with his work around the stoppages against Collingwood helping him to a rising star nomination this week.

Against: Do they try and get into other teams' heads too much rather than focus on the ball? Tactics back-fired against the Doggies.

For: Jack Scrimshaw might be ready to cement a spot in the Hawks' back line. The tall defender was a late call-up for round three and impressed with his poise and cleanliness.

Against: Still working out its ideal forward structure with Jon Patton, Tim O'Brien and Mitch Lewis three talls trying to squeeze in.

For: Trent Rivers looks a find, slotting in across half-back. The West Australian's skill level by foot will be a long-term asset for the Dees.

Against: Lacking the scoring potency which helped them rise up the ladder in 2018. That season they averaged a competition-high 104 points a game. Currently they're averaging a competition-low 37.

For: Jy Simpkin has taken the next step as a midfielder and is starting to justify why the Roos used pick 12 in the 2016 draft on him. Averaging a career high 24 disposals a game, up on 18 last year.

Against: Ben Brown is struggling to hit the scoreboard with just six goals after four matches after 64, 61, and 63 in the past three seasons. Getting double teamed and missing the injured Nick Larkey as his forward ally.

For: Charlie Dixon looks menacing in attack. His strength and vice-like marking is making him a threat whenever the Power heads forward. Leads goal-kicking with 11 majors.

Against: Lost exciting teenager Xavier Duursma to a hamstring injury, robbing them of pluck in attack.

For: Time. The Tiger train is slowing but it's not at a complete halt. The season is in its infancy and the club has time to rectify its poor form.

Against: Is the hunger after two flags in three years dissipating? Maybe it's time to get some fresh faces in the side, such as strong midfielder Riley Collier-Dawkins.

For: Can score when on song, Kicked 88 points against Western Bulldogs and 83 against reigning premier Richmond. Max King, Rowan Marshall, Tim Membery and Dan Butler will form the nucleus of their forward line.

Against: Flashes of brilliance but consistency is an issue. New-look list will take time to bridge the gap between best and worst.

For: No wonder the Swans didn't want Tom Papley to slip to Carlton in last year's trade period. His pace off the mark and creativity in attack catch opposition back lines guessing.

Against: Missing the injured Buddy Franklin in attack. Even if he's not kicking goals, he provides a presence and takes the pressure off his teammates.

For: Sometimes people forget baby-faced ruckman Tim English is only 22 and with 33 games to his name. Still working on his ruck craft and can be exposed against the league's top-liners but his ability below his knees and touch for a 202cm player is rare.

Against: Aaron Naughton will miss two months with a serious ankle injury, depriving the Dogs' forward line of a consistent marking target.

For: Boasts a top-line midfield - Andrew Gaff, Luke Shuey, Tim Kelly, Nic Naitanui and Elliott Yeo - which can arrest the team's form slump.

Against: Struggling to score which is not a trait associated with Eagles' side in recent seasons. Only kicked 46, 44 and 41 in its past three matches. Josh Kennedy hit form against Port, kicking four, but only has six for the season.
