Current Saints 53 man roster after cuts

You have created a fantasy world where Taysom has been getting all these snaps and QB and will play QB a lot this year. But it's not happening beyond special plays and the Wildcat. He is not prepared to play full time QB in this system. He has not been in the QB room on close to a consistent basis and has taken very few snaps at QB in OTAs or training camp. He's no longer a QB for this team. He's likely more of HB/FB/H-Back hybrid than anything else.
I’m saying Taysom could be a reliable third qb. He wouldn’t have to know much. He would likely be one of the best and most prepared to play third qbs in the entire NFL. Keeping four qbs on the 53 man roster is kinda strange.
