Kind of like how you said he's the EXACT OPPOSITE of what NFL teams look for in a third down back. Then when I countered the argument, you just kind of fade away.
Your definition of a third down back doesn't match what basically anyone else is talking about when they talk about a third-down back. If you wanted to have your own definition, I was just going to let it go.
A third down back is a quick, generally smaller back who excels at playing in space and catching the ball out of the backfield.
A quick Google search turned up
this article at the top of the list. It's from a couple years ago.
To help out, we'll break it down to the 10 running backs who had the most third-down carries last season.
1. Arian Foster, Houston Texans - 53
2. BenJarvus Green-Ellis, Cincinnati Bengals - 27
T-3. Ahmad Bradshaw, New York Giants - 24
Frank Gore, San Francisco 49ers
5. Steven Jackson, St. Louis Rams - 23
6. Stevan Ridley, New England Patriots - 22
7. Trent Richardson, Cleveland Browns - 20
8. Adrian Peterson, Minnesota Vikings - 19
T-9. Doug Martin, Tampa Bay Buccaneers - 18
DeMarco Murray, Dallas Cowboys
Several of those guys are every down backs. Foster, Law Firm, Gore, Jackson, Ridley, Richardson, Peterson and Martin were all the featured back for their teams. Thus the guys who were more "third-down backs" were Bradshaw (5-10, 217) and Murray (6-0, 217) who obviously turned into a feature back.
That's probably not particularly helpful but here is the run/pass ratio for all teams for 2012:
Even Tebow's Broncos threw more than they ran on third down by a noticeable margin.
Finally, catches by RBs on third down:
T-1. Ray Rice, Baltimore Ravens - 19
Ronnie Brown, San Diego Chargers - 19
3. Arian Foster, Houston Texans - 18
T-4. Jacquizz Rodgers, Atlanta Falcons - 15
Toby Gerhart, Minnesota Vikings
Darren Sproles, New Orleans Saints
T-7. Darren McFadden, Oakland Raiders - 14 Reggie Bush, Miami Dolphins
Danny Ware, Tampa Bay Buccaneers
T-10. Matt Forte, Chicago Bears - 13
C.J. Spiller, Buffalo Bills
Danny Woodhead, New England Patriots
Again, several featured backs (Rice, Foster, McFadden, Bush, Forte and Spiller). But the third down specialists were usually smaller guys: Brown (6-0, 223), Rodgers (5-6, 196), Gerhart (6-0, 231), Sproles (5-6, 190) and Woodhead (5-8, 200).
So out of all those guys, only one is within 15 pounds of how big Cross is. And I'd say they all play in space better than Cross (but that's my opinion).
