LOS ANGELES -- One was signed as a kicker and turned into an All-American wide receiver. Another was signed because a respected uncle thought he could compete at USC's level. Still another originally came in as a walk-on and was selected to his third consecutive NFL Pro Bowl while already sporting a Super Bowl ring.

It's hard to fathom that Erik Affholter, Troy Polamalu, and a former walk-on named Clay Matthews, were once considered afterthoughts on signing day, and they certainly didn't generate Cardinal and Gold excitement like Wednesday's signatures of All-America prep linemen Zach Banner, Max Tuerk, and Jordan Simmons.
