The two thoughts expressed in the headline are unrelated.
Starting with the green hair, CSN Philly talked to Dominique Rodgers-Cromartie about it Thursday (video available at that link). They call it a mohawk, a term to which I object. If you want to say you have a mowhawk, you've got to shave that head and leave a stripe in the middle. As a society we can tolerate no mohawk half-stepping, because it's just too disrespectful to Mr. T.
That doesn't mean Cromartie doesn't look good. I think the green suits him. And he certainly pulled no punches with his choice of shade. Via Larry Brown Sports, he explains the origins a bit:
"It goes back to OTAs," Rodgers-Cromartie told CSN Philly. "Me and Nnamdi were growing our hair. We were like 'let's do something crazy.' So he came in with a hi-top (fade). At first I thought it was a joke, but he was like 'come on, D, you gotta do something.' So I went with the green mohawk."
Again, not a mohawk. But that's OK. As well as he's been playing in training camp, he can call it an exothermic perm, and no one's going to quibble. The Eagles have finally moved him from the slot back to the outside, a more natural position for him. The move agrees with him. From Philly.com:
"It's hard to throw against him," quarterback Michael Vick lamented Thursday. "He's fast, man. He can jump routes, quick, smart. It's clear he should have been on the outside last year."
Hmmm. It's almost like the Eagles had a really inexperienced defensive coordinator last season. But that's all right, I'm sure he won't be back this — what's that? He will be? Oh.
Still, Rodgers-Cromartie and the defense as a whole should benefit tremendously by his moving back outside. That's where he played in Arizona when he intercepted six passes and went to the Pro Bowl in 2009. He intercepted zero passes last season.
It's a pretty safe bet that he'll improve on that this season.
