This is one of the reasons that worry me. Unless Ballard has a plan to bring in Jenson, Pugh, and try to acquire Nelson or some serious OL picks, I'm worried they're standing pat and if Luck comes back he's going to be in the same situation he was before. That being said, a much more competent coaching staff would help dramatically, especially with a scheme where Luck doesn't have to run around like a chicken with its head cut off waiting for routes to develop.
With regards to the Wrs though, even in a quick passing scheme they don't have much WR capability either. In the end Luck may be running around regardless, scrambling for his life.
