Yeah, GW or the new guy, I think QB play will be better. GW was a lot better at the end of last season than at the start. Not good enough, but getting there. With a new competitor, he will work even harder to improve even faster in the off-season.
So he will be better and, if the new guy wins the job, he’ll have to be that much better than an improved GW.
I’m more concerned with WR and TE than QB when it comes to the passing game next season. We need a couple/few guys who can dynamically adjust routes when needed, and who will fight for and win the ball in tight space. That will make the QBs more confident, which helps them throw earlier with less worry about INTs.
If the receivers don’t improve a lot over last season, then it won’t much matter who the QB is; their numbers will suck because they will have to throw late, avoid throwing into tight coverage, and throw the ball away a lot.
