4) NO NAMES, BIG GAMES:
For all the megastars and All-Pros in the Super Bowl such as Manning, a handful of hardly household names could have a major impact for their teams.
You know, kind of how Washington running back Timmy Smith did in 1987 or Dallas cornerback Larry Brown in 1996.
Denver defensive tackle Terrance Knighton (pictured) is one, signed as a free agent after four mostly nondescript years with Jacksonville. He's coming off a big-time performance in the AFC championship game against New England. That's after the man nicknamed "Pot Roast" for his rotund physique was buried on the Broncos' depth chart in training camp.
"It is going to be based on your performance, where you are on the depth chart, how much you are going to play," coach John Fox said. "All of those things, you earn or don't earn. Really, everything Terrance has done, he did (himself)."
Other players to watch for on Sunday include Seattle's Jermaine Kearse, Michael Robinson and Malcolm Smith, and Denver's Manny Ramirez and Paris Lenon.
