SUMMARY: A key factor in judging whether Chris Brown, Travis Henry or rookie LenDale White will the most playing time has to do with when they aren't touching the football -- especially on third down in passing situations. "The biggest thing a third-down running back has to have for us is the ability to pass block," running backs coach Sherman Smith said. "That’s when you get all the crazy defensive schemes. So first of all, you have to have a back who can pass block, who can recognize what they’re doing, give the quarterback time to throw the ball, and then have the ability to catch the ball." Currently, Brown is the team's best pass protector and, according to Smith, Henry and White need to improve their games in that area. "When we evaluate running backs, I think it’s real important to emphasize playing without the football," Coach Jeff Fisher said. "In order to be a complete back, you’ve got to be able to do both things, play with the ball and without the ball." What do you think about this article? Post your comments below.
