I think it's entirely possible the team doesn't know whether Mannion is ready...
He's had no snaps really in practice, but how hard has he been studying? Also, it's not like the guy came from Baylor. He played in a pro style offense and got a LOT of snaps. He even had a nice pre-look at what it will be like playing QB for the Rams during his senior season after Cooks left and that offense had issues all over the joint from the blocking to the WRs sucking.
I'm sure some will retort that studying one's playbook as a rookie doesn't prepare a QB for the NFL. And I agree. But just like that old adage about outrunning the bear... He doesn't have to play at a high level, he only has to play better than the other two. Run some heavy play action and have him throw it away if it's not there. What do we have to lose? More punts? Not sure if that's possible... :rolllaugh:
