Having walk ons and building the program is not the same as exclusively recruiting walk ons in the middle of the OL, as was suggested by Shanle, and apparently trumpeted by others in this thread.
I agree there is nothing wrong with building a walk on program, but you have to recruit good players as well. Since a financial analogy was used earlier I will offer this, it's ok to play the lottery and scratch offs (getting walk on players that eventually start), but only if you are making contributions to the 401k (bunch of good to great recruits).
I can agree with that - although I don't think that was Shanle's intention, at least not long term. He's correct that we need a big influx of talent on the defensive side, but ignoring the OL scholies isn't the right way to do it. That's why Frost got a 7 year deal!
