A source close to Fritz says that the U pulled his offer because they wanted him to commit and he wasn't ready to make that choice yet. I'm sure there's more to the story, as Rock is only a Junior, and it's still early. I have heard that Brewster only wanted 2 WR's in this 2009 class, and with Keise committing, I'm guessing that had something to do with this decision. If this is true, that leaves one spot left, for Bryce McNeal...or someone Brew has up his sleeve.
Like I said, take this all with a grain of salt, that's why I'm just posting this on the board and did not do a story on it. It is all speculation, but it's what I've pieced together - and wanted to pass it along.
