Glimmer of Hope for the Running Game?

Mack Brown had an impressive tune-up in the final preseason game. He was a practice squad player last year, signed as an undrafted free agent. However, he looked decisive in his cuts, he followed his blocking, and he showed off speed to score on the long run.

It's hard to tell how much credit to give when many of the players out there won't be on the regular season rosters. Nevertheless, there's at least a glimmer of hope that Brown and/or Robert Kelley can push Matt Jones and Chris Thompson to uplevel the running game. If not, I hope Scot McCloughan feels comfortable dialing up Pierre Thomas' number.
