Why does anyone defend Tanny?
He was terrible.
In order to compete in the salary cap era , you need players that are undervalued relative to their contracts. Russell Wilson is a great example- it will be five years before he is paid what he is worth. Undervalued players are generally found in the later rounds of the draft, UDFA, or the injured reserve list. When you draft well in the later rounds it allows you pay other proven assets at key positions such as QB & LT. Mike T was big on trading away his draft- Sanchez, Keller, Greene, SHill & Revis were all examples. He also surrendered picks on Tebow, Cro, Santonio. Revis was a score but we did give up a lot of shots on goal over the last five years. I have a hard time naming any severely undervalued Jets but there are plenty of overvalued ones such as Harris and Sanchez. Thats a failure of the GM
A new GM is bit like a new dentist- you don't know if they are any good until you start feeling the pain. Its safe to say after seven years that Mike T was bad at his job. He left us in terrible shape on the salary cap despite below average talent at the skill positions. Thats hard to accomplish.
No way Idzik can be any worse. And possibly he could end up being very good at his job. We can evaluate in 5+ years.
