I have always been a fan of what Marrone did to supplement recruiting by bringing in JUCOs and transfers. If SU was winning recruiting battles against Pitt, Rutgers & BC, it would not be necessary to go so heavily into JUCO ranks. But we weren't winning those battles, and we certainly did not in 2012.
Past impact of JUCOs/transfers was much higher than you are allowing above. Cruz was an instant starter as the blocking TE, and Weaver was about to have big impact at WR when he got injured. Hay & Tiller started for two years. MPB was the starter at DE. Diabate started and had a surprising impact at MLB.
Current impact -- Jones is starting at NT, Williams will certainly be in the rotation once he gets to campus; Clark might be starting at one of the WR spots; JUCOs are everywhere in the two deep on the defensive side and will help in rotation with the starters.
This isn't the preferred strategy -- we have to win our share of battles for high school prospects.
Please don't forget Deon Goggins!
