Jameis Winston -- SHOWERED IN CRAB LEGS ... If Drafted By Bucs

Jameis Winston will NEVER have to steal shellfish ever again ... 'cause a Tampa restaurant is promising to hook up Winston with more crabs than a Tijuana hooker -- as long as the Bucs draft him #1.

Here's the deal ... there's this place in Tampa called Skipper's Smokehouse that's FAMOUS for it's crab legs -- and the owner of the joint happens to be an FSU alum who graduated in '68.

The people at Skipper's told us they're well aware of Jameis' penchant for crab -- and want the QB to know, if he signs with the Bucs ... they're gonna "hook him up" with all the legs he can eat.
