I think it's time he move back to DE. Maybe the coaches were satisfied with DL depth and wanted more at LB. I just don't think Bronson can cover in space that well and it seems predictable that BYU is probably going to bring the blitz from his side.
I think we would be better served to have him as DE and maybe get some pressure with 3 rushers. And when we bring blitz from the LB it would be less predictable.
Somebody with more football knowledge tell me why he is better at OLB. Maybe it was worth a try, but it just doesn't seem to be working out.
