OC O'Brien 'riser' in coaching ranks

Earlier this week, all eight ESPN.com divisional bloggers assembled a power ranking of rising assistant coaches across the NFL, with a focus on up-and-comers yet to see their first head coaching job.

Patriots offensive coordinator Bill O'Brien was the only Patriots assistant coach to make the list, coming in at No. 9. ESPN.com AFC East blogger Tim Graham ranked O'Brien as his No. 4 assistant coach. He explains his decision here.

Earlier this month, CBSSports.com's Pete Prisco offered a similar ranking, but instead it was Patriots defensive line coach Pepper Johnson who cracked the top-ten list.

Which coach do you see as more likely to become an NFL head coach? Is there anyone else on the staff worthy of consideration?
