Have we had successful dips into the HS ranks w/ kids we start recruiting at this late stage? I don't think our track record there is very good either. Guys who are pursued this late in the process are typically B-list kids. They have some sort of knock, be it level of competition, poor tool or 1 gd varsity year. Most are projected to be rotational/backup players. If the eval of the JUCO is that he is ready to be that and the current roster composition suggests you need the depth, then it should be a no brainer to pursue the JUCO.
For every Bromley, there is a Burton.
I don't think taking chances on guys like Pierce-Brewster/Trejo who don't work out is a bad thing. You miss on HS, you have that scholly for 4 years at least (which isn't always the case, but should be).
Contributing vs. playing, I don't understand. Lasker, for as poorly as he played, played a number of snaps and preserved a redshirt of one of our young OL. He was obviously deemed by the coaching staff to be one of (if not the best) OL backup. Josh Kirkland, Luke Arciniega are other depth contributors.
Looking at this years sr. class, here is the breakdown of non-contributors (IMO):
Freshman - Vigille, Hale, George, Kobena, Simmons
JUCO - Funderburke (essentially), Trejo
