That is my guess. Durability also factors in. We will see.
Maybe they roll with 5 and put the rest on the practice squad. Roll heavy OL until things clear up and them bring up another
durability is great, but i'd rather have a talented guy who deals with injuries at times than an immortal fourth-stringer who otherwise doesn't look like an NFL-caliber receiver.
unless we cut them both and run with five receivers or bring in a new guy entirely (which is conceivable) i don't think there's any chance bersin makes this roster and gettis doesn't.
