Price is just going to be way too much. That is the catch-22. If you get it right, pay a king's ransom, it really doesn't matter what you give up. If you miss, you set franchise back 5 years, get fired, but we'll all still be here.
That said, if he's a franchise and all-league guy for 10+ years? I'd give up both of our firsts plus next year's without question.
