If Jerry fires Garrett and hires a new coach and has sudden success, Jerry will still get credit for hiring the new coach, same as hiring Jimmy. So I don't see it's the last thing Jerry wants.
But Jerry has patience, if nothing else. The Browns are on their 10th head coach since Dallas last won a SB. Hiring coach after coach every couple of years seldom leads to great success, even if the coaches don't do well. Lots of folks wanted Landry fired after only 3-4-5 years, but Clint stuck with him and the result was super success. Jerry has stuck with Garrett because he hired Campo and other coaches and when they didn't have sudden success he fired them and got another coach, who again didn't have sudden success. He wanted a different approach. So far it hasn't worked to the extent he wants, so I do feel Garrett is on the proverbial hot seat, though like someone said, since Garrett hasn't been officially replaced or is retiring, he's not technically a "lame duck" head coach.
IF Jerry fires Jason, will he finally bring in another Parcells, a proven head coach, and give him lots more control, or bring in another so-called puppet?
We'll just have to wait and see...
