Tim Hightower still not back to 100%

Redskins RB Tim Hightower still isn't back to 100% after last October's torn ACL.  Hightower has been a limited participant in training camp, and observers have noticed a limp whenever he walks or runs.  Hightower says he's making progress and vows to be ready for the season-opener.  “I’m just getting better each day,” he said. “I didn’t [regress] at all. I don’t think it’s any area of concern. I just went out there the first couple days to see how my body felt, and I just keep getting better. I’m still on track."  Hightower is going to have trouble holding off RBs Roy Helu and Evan Royster at less than 100% though.  If you're going to dabble in the Redskins' backfield, Helu is the back to own.
