Here are a few players that come to mind:
Dolphins - Dan Marino and Ricky Williams. Dan is obvious and Run Ricky Run was such an anthem for those 2 seasons, I have never seen a buzz like that from any Dolphins player in my lifetime. Zach Thomas and Jason Taylor can be considered here as well.
Heat - Alonzo Mourning and Dwayne Wade definitely lead the pack here but even after one season and change Lebron James and even Chris Bosh the buzz is unlike anything we have seen down here is SoFla and who can forget Shaq. I gotta throw Tim Hardaway in the mix as well.
Marlins - Mr. Marlin Jeff Conine clearly is a fan favorite and top 5 is no stretch for him. However the buzz was never greater than when Dontrelle Willis aka D-Train was taking the mound. The guy had a unique delivery and would dominate at times early in his career until teams figured him out. Livan Hernandez obviously had a huge buzz being from Cuba and helping lead the Fins in 1997 to a World Series win and Josh Beckett in 2003 was unbeatable in the playoffs. My wildcard as a fan favorite tho . . . Chucky Carr. That guy was on SportsCenter every other night for a play . . very much a fan favorite. Miguel Cabrera is the best player we ever had tho.
Panthers - I don't follow hockey nearly as much as the first 3, but 1996 and John Vanbeisbrouck go hand in hand with all Panthers fans. That was a scene and buzz we had in South Florida that was truly unforgettable. Scott Melanby was a fan favorite during that time as well but our best winger had to have been Pavel Bure. Still to this day you have to wonder why we didn't do more to keep Roberto Luongo in net, but it is what it is.
Hurricanes - Much harder to list college guys because many of these guys were here for only 3 years and then thats it. Just to name a few, I'd go Ray Lewis and Ed Reed as the guys people know and Edgerrin James, Bennie Blades, Michael Irvin, Alonzo Highsmith and Ottis Anderson as local products who were big stars at the U. QB play is well known with Jim Kelly, Vinny Testaverdie, Bernie Kosar and Ken Dorsey. Still there are plenty names I have left off but none of them really have that impact in South Florida in there hay day to give them the "buzz" needed to be on this list.
Other - Completely agree with Dwayne "the Rock" Johnson. Not really known for his days at the U, but as a wrestler and fan favorite . . . he deserves merit here. Kimbo Slice is Miami born and bred, and definitely had a buzz as his videos went viral on youtube. I have watched the buzz on Venus and Serena Williams in South Florida well before they got major. They have been down here since before 10 years old and they still live in South Florida to this day. They also own stakes in the Dolphins I believe.
Based on all that if I put together a top 5 it would be:
1. Dan Marino - Not unpassable and that is probably due to the lack of a ring, but he clearly is still the "legend" off all South Florida athletics.
2. Alonzo Mourning - The Heat weren't anything until he came. Combined with all his contributions off the court and coming back to help win a title in 2006, i had to put him at #2.
3. Dwayne Wade - "Wade County" need I say more. I'll probably have him above Zo soon and maybe Marino before it is all said and done, but the performance he gave in the 2006 finals is unlike any performance the NBA has ever seen in that kind of moment and only Josh Beckett pitching on 2 days rest to beat the Yankees in Game 6 of the 2003 WS comes anywhere close to that as an individual performance by a SoFla athlete in that type of moment to win a championship.
**Everybody's top 3 should have those 3 names**
4. Jeff Conine - The guy was an original 1993 Florida Marlin, on the 1997 championship team and the 2003 championship team and still has a position in the front office and is always on the TV broadcasts. Multiple charities in South Florida and holds the title of "Mr. Marlin". Fan favorite as the people know him as . . . Jeff cOOnine from the Marlins announcer and Niner . . . multiple nicknames always indicate fans. If he had the big time stats, he potentially could rival Marino in this list but either way it would be a injustice to leave him off a top 5 list.
5. Jason Taylor - This was tough for me and he won't be here for long as I think Lebron passes him as soon as he helps bring a ring down here, but JT deserves this spot. To me this list needs to consist of people who put in a tenure as an "icon" in South Florida Sports. Sure the Rock, Venus and Serena transplanted here before there careers skyrocketed and have enjoyed successes professionally . . . but I still don't consider them South Florida icons . . . they are more icons from South Florida and that makes a difference to me. Jason Taylor has enjoyed 13 seasons down here and would be a no brainer on this list if not for the "lack" of success the Dolphins have experienced during his tenure. He has charities tied to South Florida and despite the nonsense that some fans wanna give him for "going to the Jets" if the Fins don't offer you a contract and another team will, and that other and only team is the Jets, the man has a right to continue his career. Still he will forever be a Fin and fan favorite and rounds out my top 5.
