MUAlum04 -- I believe you are correct that Snyder would like to get academically-eligible HS kids with upside over JUCO or Prop players. However, I believe your post is unfair to a degree.
Here is why:
Snyder's First Full Recruting Class in 2006 (His 2nd year at Marshall):
Juco (5) -- Anthony Binswanger, Darius Passmore, Josh Johnson (GA Military), Aaron Johnson, Ryland Wilson
Prop (1) -- Travius Thompson (also Harvey and Booker, who are listed below in the Prep School category)
Prep School (3) -- Cody Slate, Mario Harvey (also Prop), Antwan Booker (also a Prop)
No-Shows that might have been Props[/i](5) -- DeMorris Kilow, Josh Long, Richard Nelson, Aaron Ward, Kirby Watson
These figures represent 14 of the 30 players listed by Rivals as commits
Snyder's Second Full Recruiting Class in 2007
JUCO (1) -- Montel Glasco
Prop (6) -- D.J. Wingate (holdover Prop), Jordan Delagal (holdover Prop - not officially in this class, but I will count him) Delvin Johnson, Vinny Curry (also Prep School), Jo Jo Cox (also Prep School), Brandon Bullock. (Also T. Edwards was borderline and was cleared late, and CJ Wood was questionable when he arrived).
Prep School (1) -- Ryan Tillman. (Cox and Curry were also Prep School players)
No-shows who might have become Props (3) Micah Carter (I hear he is coming but I was told grades were an issue before), Justin Footman (didn't make grades), Franchez Pitts (didn't make grades).
This year:
Several JUCO players have been offered or will be offered. Prep players have also been offered. And it is too early to tell about potential Prop players.
***I only make these points b/c these facts appear contrary to your assertion about the JUCO, Prop and Prep kids. I do believe that Snyder would PREFER to only rely on 4-year HS players who are eligible right out, but the fact is that sometimes you have to recruit based on need and availability. I do agree with you that he would like to only get those players, but that is harder said than done when you are a D-1 program in an area that is not very talent-rich with recruits.
