I'd say Boyle is the #2 QB, as it sounds like he keeps improving and knows the system, and with this off-season rookies are going to get the least amount of practice ever before a season.
And while the current trend is throw a QB in there early and often, it seems like QBs haven't necessarily always developed as well that way. So let Love sit the bench, and make him earn the job.
That's one huge complaint I had a long time ago and haven't thought of in a while, it seemed like rookies that were just given a starting spot on the depth chart DT Justin Harrell and OT Sherrod, struggled more than guys that had to earn it, OT Bulaga, DT Daniels.
So I'm all good with putting the new guys last and telling them to earn their way up... though when it comes to released, you do have to think about upside potential and development potential, and not strictly who's better now. But I'd try to make sure no rookies got the day 1 starting spots.
As for trade bait, I think this is a bad time for QB trades, as the recent supply of QBs has been larger than normal, and most teams got someone who they think might be their future.
