Henry is a throwback to a different era of heavy formations and downhill runners who used size and strength to punish defenders and impose their will. He's a rare breed of RB in today's NFL, where guys rely more on speed and quickness and who are comparatively lighter and slighter of build. He's pretty fast, too, so he could be the most complete player at the position that we've seen in awhile, more of a classic tailback.
With NFL defenses designed to matchup with spread offenses and shut down speedy receivers and shifty ballcarriers in high-volume passing attacks, having a physical beast like Henry is a major advantage against smaller linebackers and safeties. I've been saying for a little while now, I thinkwe're going to witness a renaissance of smashmouth football in the coming years as teams look to counter smaller defensive units that are vulnerable to big linemen and power runners. It's refreshing to watch as a true football fan.
