Jim Irsay has his pick of Andrew Luck or Robert Griffin III with his Colts owning the NFL draft's No. 1 selection. He's also using his Twitter account to try to play matchmaker for QB prospect Ryan Tannehill. The Colts owner called Tannehill the "hidden gem" of the draft and suggested that if a team wants to select him, it will have to talk trade with the Vikings, who own the No. 3 pick. "Tannehill is a hidden gem in this draft, a quiet secret who was always sneaking up to #3..you want him,you better talk to Zigi The Biggie!," Irsay wrote Wednesday afternoon.
