Here's my take: first, it doesn't surprise me that a winner and a man of faith who has blown up a lot of bets is hated almost universally in a gambling forum. He represents a lot of things degenerate gamblers hate, and he's cost a lot of people money to boot.
I've never been a Tebow fan personally, but you have to respect the guy's penchant for winning. He has obvious flaws, but I look at it this way: people keep saying "Denver didn't win because of Tebow" -- have you looked at his fourth quarter stats? They're through the roof. He maybe didn't single-handedly didn't deliver these victories, but he played a significant role with clutch throw after clutch throw.
He's a heady player who is tough, in incredible physical shape and doesn't turn the ball over. Football is a team game and Tebow plays into that concept to perfection. He doesn't try to do too much and would rather lead his team than put up huge stats before coughing it up late -- something plenty of other big-name QB's are great at in the NFL.
I think a lot of the Tebow hate speaks to the insecurities of fans who aren't used to seeing an NFL quarterback contribute to wins in a less traditional way. I also think that if he wasn't such a devoted man of faith, he wouldn't be hated on nearly as much.
Have to tip my hat to the guy. People love to hate on winners, and this guy's obviously a winner, so let the hating commence. Again.
