It is tough to see any really new guys making a lot of noise at San Diego State or UNLV. Both schools invested in the future last year and recruited to build a base in 2007 and 2008. They don't want to push youth on the field too early.

Other notables:

MWC X-FACTORS: First, the level of recovery and enhanced accuracy and power of Ute QB Brian Johnson's shoulder, and second, the emergence of either Shea Smith or Eric Herbort at Air Force in replacing departed QB Shaun Carney. A third factor is TCU's offense — or lack thereof.

UNDERESTIMATED: BYU's defensive line. After three seasons of starting freshmen, this may be the deepest and most talented unit Bronco Mendenhall has fielded. Gone is true freshman Ethyn Manumaleuna to an LDS Church mission, but Jorgensen — now a junior — returns as the league's sack leader. Former starter Russell Tialavea is back at nose guard after ACL surgery and joins experienced Ian Dulan, Rick Wolfley, Brett Denney and Mosese Foketi. JC guys Hola and Afutiti provide choices and competition that's been missing this decade in Provo.

LIFE VEST: Could be needed at Wyoming, where Karsten Sween's inconsistency will be challenged by senior Ian Hetrick and sophomore transfer Dax Crum. If the Cowboys find an offense and can win road games, there could be a lot of sober joy in Laramie.
