Matt Leinart is feuding with Superman actor Dean Cain

Matt Leinart is fighting with Dean Cain from Superman on Twitter after Cain's Johnny Manziel remarks.

Matt Leinart is taking on Superman in a Twitter feud that all began with Johnny Manziel and TMZ, sort of.

Former Superman actor and NFLer Dean Cain recently advised Johnny Football (via TMZ) to stay away from the Hollywood crowd, lest he end up out of the league like Matt Leinart.

Leinart heard about the advice and took to Twitter to point out that he had a much longer career in football than Cain.

The edge here has to go to Leinart, who makes a solid point about his seven-year career, although it is probably generous to call Dean Cain D-list in 2014.
