Bucks may have a glut of bigs, but they can easily remedy that through buyouts (Dalembert) and the amnesty provision next offseason (Gooden).
I don't foresee John Hammond jeopardizing cap space/payroll beyond this year, or giving up assets for a short term fix. He's been patient so far. He's done a good job of walking the tightrope of simultaneously maintaining financial flexibility, acquiring assets, AND remaining competitive despite being in a small market.
John Hammond's contract expires this year. So does Skiles'. They want to show short term improvement, not an unbalanced roster and a bad team.
Bad team? Bucks are currently the 5th seed in the East.
Short term improvement would be a colossal mistake. They can bring back Ellis, Jennings (QO), and the young frontcourt (Ilyasova, Sanders, Henson, Udoh, Mbah a Moute), and still have cap space if they simply let the aged expirings (Udrih, Dalembert, Dunleavy, Pryz, Daniels) walk and amnesty Gooden. Why deviate from the course now?
They'd do much better to keep the cap space going into next offseason, and trade a prospect and picks to land a big fish to add to the core.
