I'm trying to think of a good comparison with current recruiting situations. Take Dave DeJulius and Michigan, he committed about a year before signing day. Now imagine that Brandon Wade (PG from Skyline with mainly MM offers) has a big summer and ends up with, say, an Illinois and a Cincinnati offer. Michigan would be in a spot where it can't do much (it has its PG) and no one would be that concerned.
The trouble for OSU... Burke turned into the national player of the year in 2 years. That's not what Michigan expected at the time (was just hoping for Darius Morris's backup), but they looked genius in the end.
(Also the two years that Trey was in Ann Arbor, OSU won a Big Ten Championship, tied for 2nd in the league, made a Final Four and made an Elite 8.)
