Sanchez started one year and left early. Not much in common other than the system.
Leinert-nothing in common other than the system. Lefty, even less arm strength, not nearly as accurate, not a dedicated student of the game, lack of film study really showed up in the NFL. Intangibles sucked.
Matt Ryan-all the intangibles are there, similar arm, from a similar system. Ryan has shown a similar skillset and mental makeup being successful in the NFL. Ryan is a good picture of upside. I think a pre-shoulder injury Pennington would be the floor. Either is a drastic improvement.
All that being said, I'm not saying I think he's better than Smith or Wilson, just that I think he'll be the pick for a gunshy franchise.
