I think we'll see Hafoka redshirt and maybe even Ashworth and may just rely on Collie, Reed, Mahuika and whoever else. I think White, Koz, and Jaussi are all examples of guys who have been in the program and have been putting in the time and I think one or even a few of them will get a chance to really contribute this year.
But since we don't really need Hafoka or Ashworth this year and seeing as how they have a redshirt available, why not use it? Chambers is still a question mark in my mind. He could be redshirted too, or depending on how quickly he can pick things up in fall camp (maybe he'll make it out for summer workouts which would greatly help I'm sure) he could be an instant contributor. We've never really had as physical a receiver as him at BYU before. His combination of size, speed, and physicality would be a huge advantage if he can learn the system and run good routes.
