Three To Get Ready

These under-the-radar training camp battles bear watching by fantasy players.

Lions RB
Either '07 disappointment Tatum Bell or rookie Kevin Smith (right) will benefit from Detroit's new dedication to the run.

49ers QB
If J.T. O'Sullivan gets the nod over Alex Smith or Shaun Hill, he could be worth a final-round flier, given offensive coordinator Mike Martz's track record with other journeymen (Kurt Warner, Jon Kitna).

Broncos WR
Free-agent signees Darrell Jackson and Keary Colbert are vying to catch balls from the breakout-ready Jay Cutler.
