You have some good players that might give you a chance to compete this year, as long as you stay healthy. If you can make a trade that upgrades a starter or two, you would help your chances of making the playoffs.
Playoff Chances
Prediction
QB Analysis

Patrick Mahomes should be an okay QB1 for a 12-team league, but there will be multiple weeks where he'll make you regret not upgrading.
RB Analysis

Joe Mixon is not an ideal RB1 for a 12-team league. He will have some okay weeks once in a while, but could have more bad ones than good ones. Try to upgrade if you can.
WR Analysis

Ja'Marr Chase is an awesome WR1 for a 12-team league. He's a stud who you can rely on for consistently impressive production.
Tee Higgins is a quality WR2 for a 12-team league. He should give you decent consistent production all season long.
TE Analysis

Travis Kelce is an average TE1 for a 12-team league. He may win you some weeks, but will disappoint at times as well.
FLEX Analysis

Alvin Kamara is a solid FLEX1 for a 12-team league. His production may be inconsistent, but he should provide you with strong weeks every now and again.
Najee Harris is an average FLEX2 for a 12-team league, so don't expect anything more than average results.
Darnell Mooney is a coin toss as a FLEX3 for a 12-team league. He could be good, could be bad.
Compare vs. Average
PK Analysis
Justin Tucker is an 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 Cleveland Browns aren't the best defense, but D/STs are mostly a crapshoot. You'll probably want to stream defenses.
