Kelly will be tempted to throw less often. I think with QBs like Rees and Golson the temptation to throw the ball all over the yard is too great for Kelly.
Hopefully with a true dual threat QB, he will focus more on the run.
I think the writing is on the wall for Golson. I saw a stat last night that Golson has singlehandedly had more turnovers (22) in the final nine games than 118 teams during that time period. That's pretty staggering.
I actually think Golson is a very good QB and a fresh start might serve him well.
