The cap hasn't been "mismanaged". If anything Beane is too conservative handling the cap.
If he wanted to, he could free up $60M-$70M in space in March.
Typically, Beane has been a "pay as you go" GM compared to many.
Tre, Von and Diggs wasted a chunk of money but that was driven by injuries and Diggs doing Diggs things.
All 3 of those should have been among the "pro" elite type guys.
Overpaid some for Knox but that is not a cap killer by any means.
There was a huge turnover in starters last season and the team still performed.
As for Josh and his cap. Beane is actually using cap for a good % of Josh's AAV. As of now no cap is pushed out past the end
of Josh's contract. Compare that to Hurts who already has $100M pushed out PAST the end of his contract.
Like I said, if anything Beane is too conservative.
