Whatever you say.
He should restructure his deal. He's more suited to a West Coast offense and could be a useful back-up, especially if they get lucky with a vet like Smith or a rookie.
With the bonus he's owed, he may come cheaper than he otherwise would. Upgrades are upgrades. This team should go after any that are available and reasonably priced.
It's primarily about timing and money. The Bills track record in this regard is less than stellar. I have a feeling RW is willing to finally spend, but you need to "move out quickly."
Don't wait and pile on the offer for whomever we really like. Prospectives would much rather be in SD or the like unless we can really impress with money, quickly.
You can turn over control of a business while still maintaining an interest in it. Perhaps he's selling the team but maintaining a minority interest, or something like that.
