I would agree with this assessment. They had a revolving door at 1 CB spot and SS/FS spots were hit and miss at best. Without question the worst Iowa secondary in the last decade.
I thought he'd be in the mix at a safety spot eventually or maybe their nickel but judging from Iowa's portal...
Colorado can just un-retire the #2 after Sanders leaves for greener pastures.
As another poster mentioned, if Colorado is retiring #2 it should have been Deon Figures.
The only situation I can think of that went a little like that was Howard Schnellenberger who built a monster at Miami, won a National Championship and then left.
He took a year off and went to Louisville. 5 losing seasons in 10 years.
