I disagree. In today's high-octane pass offenses, 3rd down backs are hugely valuable.
Just look at the Super Bowl. James White was the 3rd down back and he had 2 rushing TDs (on 6 carries for 29 yards) and 14 receptions for 110 yards and another TD.
Now, that was obviously a performance and a game for the ages, but still.
Check out Danny Woodhead's stats in 2015. He had 81 receptions for 756 yards and 6 TDs, and 97 rushes for 335 yards and 3 TDs. In my PPR league, that was good enough to make him the #5 RB overall! The #5!
You might think that the Danny Woodhead comparison is some kind of insult to CMC, but it's actually a huge compliment. Woodhead has often been huge in PPR leagues when healthy.
There's no shame in being a new, younger Danny Woodhead. In fact, the CMC fans out there ought to embrace the fact that their guy is Danny Woodhead 2.0!
