When Mike McCarthy confirmed super-utility man Ty Montgomery is officially a running back this week, the very first thing I thought of was his jersey number. Per NFL rules, once the season starts, you’re stuck wearing that number. Montgomery has indicated that he’d like to change numbers in the offseason.

The Packers had a similar case where a player transitioned from one position to another – Spencer Havner. Havner, a linebacker at UCLA, joined the Packers’ practice squad in 2006. Searching for a way to finally break onto the 53-man roster, Havner converted to tight end before 2009’s training camp. As a linebacker, he wore 53 and switched to 41 after converting to tight end. He caught seven passes in 2009 (four went for touchdowns), and was on the roster for Super Bowl XLV.

If you’re a Ty Montgomery fan or a collector of rare sporting goods, a Montgomery jersey with the number 88 may be a good Christmas investment.
