Free pizza for a bunch of guys who weigh an average of about 300 pounds sounds like a recipe for a pizzeria to close its doors. But when the pizzeria owner is Minnesota Vikings tackle Matt Kalil, taking care of teammates is just the cost of doing business.

Twincities.com reports Kalil, 300 pounds-plus himself, is treating his Vikings teammates to free food during training camp at his Pieology restaurant in Mankato, Minnesota. The Vikes have 21 players topping out at more than 300 pounds. Along with Frank Kalil, hid dad, Matt owns three Pieology Pizzeria outlets in Minnesota, including stores St. Paul and Maple Grove. His Mankato shop, just block away from the practice field, only opened in October. This training camp marks Matt's first chance to feed his fellow footballers. "If they bring their little keychain thing (that players have), they get to eat for free over there. It's a good deal," he says. So what's the up side for his Pieology business in free pizza for giant athletes? "If they go in there and the fans see them in there and we just end up getting more customers, it works out for both of us," Kalil adds.
