Team Analysis
Overall Reaction

Roster
Outlook
This is an inferior team that almost certainly won't make the playoffs as is, unless you get some unexpected performances from multiple players. Therefore, you should look to make some trades ASAP and you should also be very active on your league's waiver wire.
Playoff Chances
Prediction
QB Analysis

Aaron Rodgers is a bad QB1 for a 12-team league. If you stick with him, he will make you wish you upgraded all season long.
RB Analysis

Tony Pollard is a terrible RB1 for a 12-team league. You should make it your priority to upgrade here.
Tyler Allgeier as your RB2 in a 12-team league is a nightmare scenario. You can't afford a serious weakness here, so try to upgrade ASAP.
WR Analysis

A.J. Brown isn't the best WR1 for a 12-team league, but he might be able to provide you with enough good games to get away with it.
George Pickens is just average as an WR2 for a 12-team league. He'll probably help your team more than he hurts it, but no guarantees.
TE Analysis

Cole Kmet is a horrendous TE1 for a 12-team league. Prioritize upgrading this spot.
FLEX Analysis

DK Metcalf is a stronger FLEX1 for a 12-team league. There could be rough patches, but expect a good overall season from him.
Compare vs. Average
PK Analysis
Matt Gay is a slightly below average kicker.
In general, don't spend much time worrying about kickers. They are too unpredictable. Try to find a kicker on a team with a good offense. And if he's playing in a dome, even better.
DEF Analysis
The Miami Dolphins aren't the best defense, but D/STs are mostly a crapshoot. You'll probably want to stream defenses.
