Cowherd has been absolutely amazing this year, his picks effect the Vegas line. If you do a search on Colin Cowherd Blazing 5, the returns include a lot of betting sites that mention Colin. To be honest, I have a lot of respect for the guy, he's a work-a-holic and knows his stuff. I wouldn't want to hang around him because that voice and attitude would wear thin very fast, but I respect the man.
Here's a quote from a guy that hates him about his picks:
"Each week, Cowherd offers his "Blazing Five" NFL line picks. With those picks, he's 35-15 on the season—70 percent accurate. That's essentially unheard of. The Las Vegas Hilton has a "SuperContest" in which the city's best sports gamblers pick five games a week. The best entrant in that contest is 33-15-2, or, in other words, not as good as Colin Cowherd."
Also, here's a link to a page with his previous Blazing 5 picks. He's full of himself, but he has every right to be, his picks are phenomenal.
