He had a bad game earlier this year, where he missed 2 FGs and 2 PATs, and was subsequently waived.
He then got picked up by the Colts a week or two later, and then was traded to the Rams 2 months after THAT, and then went 3-for-3 in PATs, and 2-for-3 in FGs — including the game winner — in a game against the Buccaneers.
