That's actually not correct. Ellis is bigger and is stronger. Heck, Ellis benched 225 34 times and called it a disappointment. Ellis weighs in at 306 to Dorsey's 297.
I do not think much separate the two in terms of pure talent. I think Ellis plays with better leverage and is the better pass rusher of the two. I think Dorsey uses his hands better. They're really identical. Both have non-stop motors although Ellis seems to have better endurance throughout an entire game. But I think the one thing that separates Dorsey, if you had to choose between the two, is his passion for the game. The guy plays with heart and has a sheer desire to succeed. As I heard Marshall Faulk and Soloman Wilcox allude to today, you really cannot quantify heart and desire. It may not show up in a workout but it will show all the time on the field and prevent a guy from being a bust.
