Tim Hightower

If Redskins RB Tim Hightower isn’t yet at full strength, the starting job will come down to Roy Helu and Evan Royster.

Both showed some flashes last season, but Redskins coaches still have some questions about Helu. For one, although he offers that threat to break a big run, he struggles to consistently pick up chunks of yardage. The Redskins would like to see him do more than just take what’s there and be able to make something out of nothing.

There also are questions about Helu’s durability. Injuries hampered him late in the season and kept him out of most of this offseason’s OTAs. Shanahan said the questions about Helu’s durability will remain until he can prove otherwise.
