I'm going to say if he went 8-8, yes. 7-9, no. He's out.
Look at it like this...
If Cam doesn't throw into the dirt against Seattle, we'd have a shot at 8-8.
If Smitty does not slip against Chicago, we'd have a shot at 9-7.
If Cam does not fumble against Dallas, we'd have a shot at 10-6.
If Nakamura wasn't so stupid against Atlanta, we'd have a shot at 11-5.
I could go on and on. Yes, there were some stupid coaching decisions. But we have also had a lot of bad luck in terms of late screw ups by the players on the field. I say give Rivera another year if we finish strong by winning these last three. Remember, Rivera did say that he would make personnel changes if he could, Marty just would never give him the types of players he wanted.
