"I’m a better runner," Blue said, when asked what he's improved on. I’m more patient, learning from Arian and him mentoring me, critiquing me every day at practice. Just teaching me how he runs and what he’s seeing out there when he is running. I would say I’m much improved in that.”
We've so far been talking about Blue as mostly a first- and second-down back, but he's been working on being more versatile. A few months ago, Foster said he was working to turn Blue into a three-down back.
Texans coach Bill O'Brien agreed that Blue's running has improved and he also noted improvement in blocking and blitz pickups.
"Blue can play on third down in certain third-down situations, no doubt about it," O'Brien said.
The article says that Chris Polk will "definitely be in the mix,' and that the Texans don't view Jonathan Grimes as "just a third down back." Blue holds the lead at this point, but Polk is the most interesting prospect if he can stay healthy. He had back to back 1,400-yard seasons and owns a 4.7 YPC, but is already dealing with a strained hamstring in camp.
