DGB got some time with the first team before putting on a clinic with the twos.
It certainly looks like Dorial Green-Beckham has been putting in the work. The Titans made Green-Beckham the 40th overall selection in the NFL Draft, despite missing the entire 2014 college football season. It was a risky pick on a few different levels, but for now it looks like DGB is on the right track.
Full disclosure here: I was iffy on Green-Beckham through the draft process. He always has been a physical freak. Size, athletic ability, flexibility -- it's all there.
