You should reread. He didn't compare Odrick to Spiller. Why would anyone compare Spiller to Odrick anyway? If I did, I would say that Odrick is a much better tackler, can get off a block way faster, is stronger at the point of attack, is much more experienced at reading plays, and can actually rush the passer. Spiller is a crap DE, good luck if you’re counting on him.
