The Steelers announced that they have signed former Cincinnati Bearcats running back George Winn to the practice squad. Winn was touted as having great vision and explosive up field cuts prior to the draft, and is someone who could fit well in a ZBS. Here’s one scout’s take on him: http://www.optimumscouting.com/draft/articles/looking-for-the-next-alfred-morris-here-s-the-top-zone-blocking-running-backs-to-be-picked-after-the-top-100.html
Winn was signed by the Texans as a UDFA this spring. After being cut by the Texans in May, the Patriots signed him in June and released him during their final roster cuts. He was signed to the Raiders practice squad a couple weeks ago, and released last week. He is 5’11” and 210 lbs.
