You're right. It's not as if he signed Lyle, LJ, Kennard, Benton, Maggitt, Ruemp, Haughton, KO, Burris, Collin Franklin, Schwartz, Sed Johnson, Darius Darks, Tiller....
He said "deserves credit" as in, SOME credit, not all of the credit...
The great unknown is, would we have got those or equally as good players without Chizik?
Should he get some of the credit, I personally say no because he couldn't even win with the player he brought in. All the credit goes to Rhoads for developing those players, coaching those players and putting those players in the system that would win games.
Giving Chizik credit for this season would be like giving the guy who sold the piece a land that the first Wal-Mart was built on credit of creating the worlds largest store chain. Only in this case Chizik paid to get rid of it.
