We asked AP pro football writer Barry Wilner to pick five key players for each team in this Super Bowl. You'll want to pay attention to these guys on Sunday.
Kaepernick, Crabtree, Gore, Aldon Smith, Patrick Willis
-MICHAEL CRABTREE (WR, JERSEY NO. 15): Matured this season and became a true No. 1 receiver. Led team with 85 catches, 1,105 yards and nine TDs. Good after catch, but needs to consider better ball security.
-FRANK GORE (RB, JERSEY NO. 21): Career rushing leader for franchise, as dependable as they come. Strong, can pound through line, but also has quick feet to cut to open space. Had 1,214 rushing yards and eight TDs during season.
-Aldon Smith (OLB, JERSEY NO. 99): All-Pro sacks machine. Not as good as he needs to be in coverage, but is raw. Then again, why not rush him every play? Great burst off the line, big wingspan and maneuverability.
