Regardless of whether they turn out to be or not, it's easy to say these moves were mistakes. It takes no critical thinking to parrot this popular view and offer nothing more, which, without hearing the interview, is what I'm assuming happened because it fits the Ryan family MO. It's Rex's comments on the Bills-Jets game, redux.
The jilted Ryans will never acknowledge that if they were better coaches they wouldn't have been fired 4 times in 2 years, collectively, because it would mean finally accepting responsibility for their shortcomings, which is not in their DNA. Instead they will stand together with their "us against the world" approach and take their cheap, mindless potshots against all who have wronged them at every provided opportunity.
He's probably just mad he can't afford to give a go-fer $1000 per week to stock his junk food drawer anymore, the fat, useless POS.
