Bobby Bowden joined the growing chorus taking Jameis Winston to task for his off-the-field shenanigans.

The former Florida State coach said Thursday it’s time the reigning Heisman Trophy winner begins acting his age.

“Jameis has to grow up,” the 84-year-old Bowden told ESPN. “He does things kids in grammar school would do, or kids in junior high would do.”

Winston was suspended for the Clemson game Sept. 20 for shouting “offensive and vulgar” comments in the student union. Florida State is looking into whether Winston was paid for signing autographs, an NCAA violation. And the school has announced a disciplinary hearing to determine whether Winston violated Florida State’s conduct code in an alleged assault of a Florida State coed in December 2012.

Bowden’s comments come on the heels of former Hesiman Trophy winner and two-sport superstar Bo Jackson — who hails from the same Alabama city, Bessemer, as Winston — saying his advice to the star quarterback fell on deaf ears.

If Winston doesn’t cut out the distractions, Bowden believes he’s “going to make it mighty tough on himself. I think his draft status already dropped way down.

“But you know what’s amazing to me about him? I don’t care what goes on off the field, once he gets under center, he blocks everything else out. It doesn’t affect the way he plays.”
