Gamble had hinted at a "surprise" coming on Friday in a late Thursday tweet, and retweeted both 2017 quarterback commit and vocal class leader Jake Allen and 247Sports reporter Ryan Bartow, who broke the news of Gamble's commitment, on Friday night.
Gamble is rated as a three-star prospect by the 247Sports Composite, and seems to be at the high end of that range. ESPN rates him as a four-star tight end, though ESPN also still shows Gamble as a Miami commit, something he hasn't been since an early March decommitment.
Regardless, Gamble profiles as a hybrid wideout/tight end at the collegiate level, and he has the frame (he's listed variously at 6'3" or 6'4" and around 220 pounds) to fit that role. His highlight reel suggests to me that it might fit him, too, as he's got the power to vex corners and make hay as an in-line blocker, but the quickness to get past linebackers and safeties that could cover him if he flexes out of a formation.
Gamble is Florida's fourth 2017 commit, joining Allen, wide receiver Daquon Green, and offensive lineman Kadeem Telfort. Of the quartet, only Tampa native Green is from outside Broward and Miami-Dade Counties.
