If the OLine coach can keep the progress going then Hall/Romney/Conover/QB4 will have a fighting chance. Losing Milne hurts, but Romney is not chopped liver and there are players in the program who could be great at WR. TE is loaded....just loaded and Allgeier was special last year. It will all come back to the OLine because if they get it done BYU will have every chance to win 8-9 games.
I agree that BYU doesn't need to "replace" Zach with Zach....and if ARod is worth his salt then he will set the scheme to favor the starting QBs strengths, not force him to do what Zach did.
