Yesterday was Tebow's 2nd INT of the year -- in nearly 200 attempts.
He's lost 3 fumbles in 94 carries this season. He's averaging 5.4 yards per carry in his career so far over a span of 137 rushes, and he's lost 3 fumbles total in that span.
Again, I'm not a Tebow fan by any means -- but you can't argue with those numbers (even if you want to go beyond the wins vs. the losses). Is he the sole reason for the Broncos' win streak? Of course not. But that's also the beauty of it.
