"Jeopardy" phenom James Holzauer says if he had to compare himself to a pro athlete, he'd DEFINITELY go with DeShaun Watson ... because he can do it all!
Holzhauer -- who's chasing Ken Jennings for most winnings in "Jeopardy" history -- appeared on FS1's "Lock It In" on Tuesday to talk about his pre-game show life as a pro sports bettor.
During the show, Holzhauer said he was a hardcore online poker player before making the jump to sports gambling -- but now he puts together complex mathematical models to find and advantage when it comes to wagering on games.
