Maybe, but what would have have done? Maybe the team gives up on him and we have one terrible year, after which we let him go and hire a new coach to use our high draft pick to find a new QB and rebuild?
Would we have supported him with expensive free agents? No, because he didn't earn that and we are tanking. Would that have been fair to Gase? I suspect he would want the extra year and accept the challenging conditions. If he turns that team into a winning team, maybe he IS the answer we're looking for at head coach? If not, well he would now have 4 typical NFL years that included 3 years to build and hone his team with the support of the front office and one year not really earned where he had to do it without the support of his front office.
If he fails, that's gotta be on him, even without the front office's support, as he was only promised 3 years, he had a losing record, and finished his last season having dug himself a hole with the players and producing a losing season. If he succeeds then he really proves his metal and it means he somehow won the trust of the players back. That seems like a pretty good scenario to me. At least I see it as preferable to what we have now, an attempt to hire a lame-duck 1 year coach with the hope he'll sacrifice himself to tank for one year so that someone else can get the glory.
