When will enough be enough?

MINNEAPOLIS -- I doubt Minnesota knows about the apparently serious injury to New England receiver Wes Welker in the Patriots’ meaningless game at Houston. And I don’t think it would change the Vikings’ thought process one way or the other.

But with the Vikings leading the hapless New York Giants 17-0 early in the second quarter, I wonder if they’ll consider removing some of their key players -- by halftime, if not now. By key players, I’m talking about those they couldn’t come close to replacing in the playoffs: quarterback Brett Favre, tailback Adrian Peterson (who is back in the flow of the offense), left tackle Bryant McKinnie and defensive end Jared Allen.

This game still has meaning for the Vikings: If they win and Philadelphia loses at Dallas, they’ll have the No. 2 seed in the NFC playoffs. But if nothing else, the Welker injury has given us a conversation topic for the rest of this game.
