So the transfer portal and coach steeling window is horrible. And the CFP starts way too late.
So this is what i would do. But the future the season for NFL and CFB is gonna change soon.
Lets say, NFL goes to 2 preseason, 2 bye week, 18 games.
CFB goes to 14 games 2 bye weeks, no conference champ game. And the CFP is 4 rounds
So the calendar would be
Mid July: NFL training camp/ CFB Fall Practice
4 Weeks before Labor day: NFL HOF game 2 preseason weeks fallow.
Labor day weekend: NFL cut down week/ CFB week 1 (everyone plays no week 0)
Week after labor day: NFL week 1.
Mid December: NFL week 16/ CFB playoffs round 1. (CFB Coaches may be interviewed but must remain with current team)
Mid January: NFL week 20/ CFB champ game
1 week after National champ game: College players must declare for NFL Draft, Coaches may be signed to new Team.
2 weeks after Nat champ game/ transfer portal opens
4 weeks after Nat champ game: ProBowl, Senior Bowl, Transfer portal Closes.
Presidents day weekend: Super Bowl/ National high school signing day.
Early/Mid March: Combine, Players in the Portal must sign to a new school or revert back to their original school. NFL Free Agency
Late March Early April: CFB Spring Camp
Late April early may: Draft
Keeps the NFL and CFB out of each others way, keeps it fair for everyone.
And yes that means the “off season” is only Mid May to Mid July
