Especially, worse case scenario, a FG ties the game. While he's streaky, we know he CAN hit from 50+. I take 50+ seconds and a timeout or two every time over thinking I'm stopping them from the 6 inch line.
Call timeout, let them score, then have time to go score yourselves. I remember watching Don Shula do this and people thought he was nuts.... until Marino drove them down the field and won the game.
