With an inexperienced QB, it seems like there's often a receiver he develops a comfort level and a rapport with. For what it's worth, I think I remember reading/hearing that Lindsay and Perich were hanging out together. Might or might not be true, and it might or might not be important.
Also, some receivers seem to have a knack for finding the open spot in the defense and showing their numbers to the QB. The type I'm thinking of catches a lot of short throws when the QB is under pressure and/or has run out of options — a safety valve. I get the impression that Loya is that type of player.
It will be a really interesting season.
