I would argue the Bidwill issue is larger than Kyler however it is an issue. Ask any coach if they’d rather have a 25 year old mercurial QB who has shown flashes of greatness but has never put it together or an owner who makes you watch film together weekly and has a front row seat in the draft room and they’d all pick the QB.
And with and the recent 15 months as you mentioned it’s really easy for a coach to win that internal battle over Kyler right now. K1 could be off the roster easy in 2 years, you’d still have your weekly film sessions with Mikey for the rest of your career.
Coaches like to coach, not play school teacher to the trust fund owner.
