They could be great. I definitely think Vontae, when all is said and done, will be a pro bowl corner. Like most people, I wasn't sold on Smith early last year, what with the benching and all, but wow when he came back into the starting lineup I definitely feel that Smith was better in coverage. His closing speed was better than I originally thought, and he became more physical with wideouts/TEs in the first 5 yards, something I wasn't expecting. That NYJ game is what sold me on Sean - even though he dropped a lot of picks, he was always in the perfect position to make a play on the ball.
Entering their 3rd year, it sounds like they're more focused then ever, and hard at work. I love the talk coming from them this offseason about being the best tandem. If there is a position where you have to play with confidence, it's corner. I hope 10 years from now these guys are still playing, and they're playing for us.
