Not saying it can be anywhere close to the same situation, but the Patriots had a top superstar round 1 QB in Drew Bledsoe, that I also believe was on a new contract, gets hurt, and a 6th round backup QB took over by the name Tom Brady that allowed Pats to go for a time, a cheaper starter.
Not saying Ewers is going to be Brady Level good, but until we give him a shot, we will never know what level of talent we have with him. They need to wake up, and make Ewers the backup, and give Tua very little rope to prove himself in, he starts being inconsistent, bring Ewers in, and forget Tua until Ewers gives you reason to bring back Tua.
