Well, I'd answer with D-Lo didn't shut down to T.O. He contained him. 5'9" Willie Williams shut down T.O. back in 2004.
I agree that being 5-8 doesn't help you much when it comes to match ups. There are few quality corners under 5-10 nowadays, most are just nickel backs. Aaron Glenn, Antoine Winfield, and Dre' Bly represent the cream of th crop, and all are 5-9.
But what I really disagree with is the notion of not drafting a good player just because of his lack of size, and drafting a lesser player just because of his size. As I understand it, it was Jennings rather than DeMario Minter who was tasked with taking on the opposing teams top wideout at Georgia. Which IMO indicates Jennings is the better player. But of course, people would rather draft Minter becuase of his size (5-11) rather than Jennings.
I'm not saying that Jennings should our one and only hope to supplant Webster in the starting lineup. But at this point, Jennings has the upside to be a starting CB in the NFL. He seems a lot like Dre' Bly if you ask me. Bly came out of school with blazing speed, and had a great career at UNC, but didn't have as good a senior year. His stock fell because of that and his lack of size. But since he has grown into one of the better cornerbacks in the NFL. He makes up for his lack of size with speed, ball skills, and confidence. Jennings could be that type of player. Bly had to ride the pine for 4 years before he really got his chance. Maybe Jennings will have to do the same, but at the very least it secures our nickel position for the long-term.
When you look at which rookie cornerback was the best in last year's class, you discover it was 5'8 1/2" Darrent Williams who ran a 4.3 at last year's Combine. Better than the likes of the 6-0 guys Antrel Rolle and Carlos Rogers. That's saying something.
I just hate the notion that you don't draft a guy because he lacks size. Guys like Steve Smith, Warrick Dunn, Dre' Bly, and a wealth of other players clearly show me that I'd take a chance on a smaller guy than a big monster first because the smaller guy has been told all his life that he was too small, and therefore he knows how to work and overcome. I'd rather have a team full of those guys than your Plaxico Burress and whoever else out there have the "beyond prototype" size.
