Exactly. Dumb decision at the time if you weren't ready to follow through with the next step should the decision work out to be correct.
A great time to pay Top-5 money for the next three years for a Top-5 RG is if you have a QB who is in his prime and you have a sub-par Center and a sub-par RT. Bengals are screwing up turning away this sure-thing. But, when the bar is set lower than any franchise in the NFL (hat other franchise would keep an 0-7 HC in the playoffs coming off a disastrous season where they finished five games under their predicted finish), what do the Bengals have to lose. It's not like they won't continue to reap the benefits of the most lopsided stadium deal in NFL history.
