Really, if a team picks him up, you really have to consider him like a rookie because the Rams didn't run a NFL offense. He has never ran the majority of routes that would be asked of him. It is all the first time.
The Rams ran the invincible in the rain offense which only features a few passing plays for the majority of the game.
I don't know how good he is, but if you are going to sign him, you have to treat him like a rookie or it was pointless to sign him in the first place.
I do know he was horrific at 50/50 balls and judging a pass and making adjustments, but he seemed to have excellent physical ability.
