Cundiff is up against the Lions which is always a good matchup for any offense. That being said means he will be kicking a lot of extra points and not field goals. Prater has went 6 games without missing a kick, hes playing in a dome and its a good chance the Broncos will be stopped before the goaline. I'm leaning towards Prater here yet Cundiff is almost guaranteed points. Hope this has helped out and good luck on sunday.
