WATCH: Marcell Dareus surprises Bills fans as repairman

Marcell Dareus has a pretty great day job as a defensive tackle for the Buffalo Bills. Not to mention, he's also one of the best at what he does.

If Dareus wasn't an All-Pro defensive tackle in the NFL, though, his fallback career may have been in the windshield repair industry. Dareus had his hand at fixing a few cracked windshields thanks to Safelite AutoGlass, while surprising a handful of unsuspecting Bills fans in the process.
