Even though the 2004 class had two linemen (Incarnato and Kadous), both of them ended up transferring out (Incarnato to U. Mass, Kadous to Arizona).
While there were enough upper classmen to hold things down in 2005 and 2006, there simply weren't any true juniors or seniors ready to handle the burden in 2007. Going against polished rosters who had plenty of talent along the 2 deep was essentially the same as putting your JV team against the top notch varsity teams.
Charlie managed to pull off a pretty impressive feat, though, bringing in Paul Duncan and Mike Turkovich at the very last second into that class of 2005, both of whom served as capable starters. There weren't any 4 or 5 star linemen available out there during those waning moments, and he still managed to get in a couple of 3 star guys who turned into serviceable players for us.
