Future NFL stars started living the good life before the league draft kicked off Thursday. No. 1 overall pick Eric Fisher of Central Michigan took over a private room at STK Wednesday night to celebrate with friends and family. A spy said a group of 20 — “from Fisher’s best friends to his grandmother, in her 80s” — circulated in an upstairs room. Fisher also rang the closing bell at the New York Stock Exchange while in town and found time to shoot a Tide ad. “For a kid from Rochester, Mich., it was pretty incredible,” said a spy. Fisher is repped by super-agent Joel Segal, who also reps No. 8 pick Tavon Austin and No. 17 Jarvis Jones through powerhouse agency Lagardère. Jones was spotted at the restaurant The General Greene and signed an endorsement deal with Subway. Also seen was No. 2 pick Luke Joeckel at SL nightclub and Texan Lane Johnson, who went fourth in the first round and took over Brother Jimmy’s in Murray Hill with his family — who all wore 10-gallon hats. The No. 16 pick, E.J. Manuel, was also at the barbecue spot.
