Jarrett, Johnson step up in Week 13's biggest games

The opportunity is there every Saturday. Some players seize it. Others let it slide away. Here's a look at the players who shined or slipped in Week 13:

Stock Up

Dwayne Jarrett, WR, USC
Jarrett proved to be overwhelming for the much-maligned Notre Dame defensive secondary on Saturday night. Jarrett has been hampered by injuries this season and was listed as questionable (concussion) heading into this game. However, the junior wideout finished with 132 yards and three touchdowns on seven receptions in USC's 44-24 win at the Coliseum. If Jarrett and Co. can take care of business against crosstown rival UCLA Saturday, it should seal the deal for a USC-Ohio State matchup in Glendale, Ariz., on Jan. 8.

Ian Johnson, RB, Boise State
Johnson's performance at Nevada was inspiring. The sophomore running back sat out last week's game because of a collapsed lung, but he suited up for Boise State's key battle against the Wolf Pack on Saturday. Johnson wore a bulky flak jacket to protect his cracked ribs, but he still ripped off 147 yards and three touchdowns on 31 carries in the Broncos' decisive 38-7 victory. The win essentially clinches Boise State a spot in a BCS bowl. Also, in a year with few legitimate Heisman candidates stepping up down the stretch, Johnson deserves consideration for an invite to next month's ceremony in New York.
