They have great talent on offense. They have Sterling Shepherd who is one of the best WR2s in the league and they just drafted Evan Engram in the first round and he will be a great mismatch weapon for them. Their problem last year was that pretty much all of their receivers got injured at some point. They were fielding WR4s and WR5s on their roster as WR1 at some point.
Part of the problem with Brissett holding on to the ball too long was being scared of making mistakes. When he first started he did throw a couple of game losing picks. Not getting any help from the offensive line nor the running game did nothing for his confidence either. As the season went on he was playing not to lose games instead of playing to win. Getting leads just to see your defense not play well enough especially in forth quarters to hold a lead. All of these factors played against him.
Just remember Peyton's first year? Look, I am not calling him a Manning but it is not unusual for first year starters to struggle with the same problems we seen out of him.
He was thrown into the mix and didn't even know half the playbook. Learning on the fly is not easy when you are playing at the same time. He was basically a rookie even he had started a couple of games but he was in a great system on a complete team and wasn't ask to do too much.
Brissett needs to work on his mechanics and IMO that is where Frank Reich comes into play.
I think with a healthy Luck, and if Barkley is there, they will feel it's easier AND quicker to build that high powered offense that they invision rather than a very good defense.
I doubt they can achieve both in this offseason.
The Defense will have to take a backseat to the O for a while.
