You'll hear no disagreement from me here.This is the exact reason why wins should not be a QB stat. I said the same thing a year ago after the Stafford/Goff trade. People were using wins to credit Goff and knock Stafford. The value of a QB should be based solely on talent/merit but the circumstances around them (ie overall team talent and franchise) may affect wins.
Jimmy is an average at best QB in the NFL, to me he's slightly below average. There are some teams though that have horrendous QB situations and he would be an upgrade over what they have. But no way in hell I'd ever give up a high pick for him.
