MANKATO (AP) — Andrew Sendejo opened the mailbox one day this spring and found it overflowing with envelopes from Rice University, his alma mater.

“I was thinking they were all my parking tickets,” the Minnesota Vikings strong safety said. “They finally found my address.”

Ah, but Sendejo didn’t need to worry. This was a much better haul: a hand-written thank-you card from every player on Rice’s roster in appreciation of Sendejo’s gift to the program for a nutrition center in his name . Coach David Bailiff, who took over the Owls in 2007 for Sendejo’s second season, directed the gesture.

“I thought it would be right to donate more than just the minimum,” said Sendejo, whose contribution became a part of a new facility for the football team that opened last year , one he hoped would inspire other alumni donations. “You need to take it upon yourself to give back. Rice is a special place. You really appreciate it after you’re done.”

The Vikings have gradually grown to appreciate Sendejo, too. For once, they’re not actively seeking competitors for his spot in the starting lineup next to Pro Bowl free safety Harrison Smith.
