In general it's unlikely that any player will do that, not just Carr. It happens on occasion but its not common. In that I don't blame him. If it's your last chance at a big payday anyone would do the same.
NFL= Not For Long, yet he has somehow manged to buck that trend. Agreement though. He is next likely to be a bridge or a clipboard holder. It's possible he is already a bridge QB now. That he has avoided that so far speaks to the state of QB play in the NFL, not him.
Agreed to a degree, more apt description is Ryan Tannehill though.
If the NFL is led to believe what happened last time it was down to the Saints and the Jets?
