Pers, I don't agree with your statement that OL is hard to predict. Seems Harry has done a very good job of targeting and recruiting, and most have developed as expected. Frankly, I think OL performance is easier to project than DL. JMO
Telx, not sure how you can say that out of HH's recruits only Elmer has played significant time. Elmer, McGlinchey and Nelson are all set to be starters and there are high hopes for them on the OL this year but their success is anything but a given over the course of the season.
Sal, I should take Harry out of the discussion. My point wasn't about Harry per se, but rather my opinion that individual OL performance is much more predictable than Pers opined. I'm talking about college football in general, not just ND OL.
