What else are you going to do if you are Indy? I think it's easy to say Luck won't live up to they hype, because the hype is so enormous. They could keep Manning (if healthy) and draft Blackmon (a WR at 1?) or one of the OTs. Do you trade the pick? Do you draft RGIII? If I'm Indy, I draft Luck. It's all a gamble anyway.
