At Colorado, Monday morning began with second-year linebacker Shakaun Bowser entering the NCAA transfer portal at 8:14 a.m. local time.

Wide receiver Montana Lemonious-Craig, one of the breakout stars of the Buffaloes’ spring game on Saturday, entered a few minutes later. Backup offensive lineman Jackson Anderson was next. And then safety Tyrin Taylor, a 10-game starter last year.

At noon, it was time for the big roster purge: 11 scholarship players became available in the transfer portal in less than an hour.

By the end of the day, 18 players were in the portal.

Deion Sanders is pursuing the most dramatic Year 1 roster flip we’ve ever seen in the transfer portal era, and he made that perfectly clear on Monday. Since his hiring in December, Sanders has never been shy about his plans to radically overhaul his roster. After a 1-11 season, the program needs all the help it can get. The new staff has imported more than 40 newcomers from Jackson State, Sanders’ previous school, and from all over the country. And they’re far from finished.
