I really don't care who thought what about Colombo or Petitti. I just care about how each is playing now. What pleases me about both is that they have a stubborn tenacity to win the job. Each has a great work ethic, and each is big & strong. I suspect strongly that Petitti didn't get much help on his footwork while at BC. He worked on it all off season, & continues to improve in that area, if a bit slowly. Colombo is not as massive as Petitti, but has more of a mean streak.
My thinking is that BP will have big Rob starting in Jacksonville, with Colombo as his backup. I don't think Colombo is all the way back from his injuries. By that, I mean mentally. It's going to take him another half-season or so to truely trust his knees, and his skills. Once he gets there, & I hope it's soon, he will be just as good, if not better than Petitti.
