You can often hear football players talk about “flipping the switch,” or “letting the other guy out,” when they step on the field. Some believe this violent game demands an alter ego of sorts, a different demeanor between the lines than the one they’d carry down the street or into a classroom. You look at Michigan State linebacker Cal Haladay out there, and it’s actually a pretty accurate representation of his personality. No gloves, no sleeves, no elastic bands. Not even tape on his fingers or wrists.
