Howie Schwab speaks at the ESPY Golf Pairings Party at Saddle Ranch on July 9, 2007, in West Hollywood, California. 

"Howie played a vital role in my career -- his incredible research was so valuable for decades," ESPN analyst Dick Vitale said in a statement. "Howie's loyalty & dedication was so special. His passion & love for sports was off the charts. Most recently he was ecstatic with the UConn Huskies going back to back and was also thrilled to see Rick Pitino bring back his beloved St. John's to prominence."

Aside from being the star of the show, he was a coordinating producer for "SportsCenter" and "Outside the Lines."

St. John's, Schwab's alma mater, paid tribute.
