I think calling Tyson Gay pathetic and overrated is a sign of a 4th year fan (Pay attention in Olympic years). Bolt has obviously burst onto the scene, but last year Gay won the World Championships 100, 200, and was on the winning 4 x 100 team.
He injured himself less than two months ago, and even though he was back in shape, it wasn't his best shape. It's hard to overrate someone who swept the sprint titles at a world championship meet, including defeating the then-world record holder in the 100, Asafa Powell.
As for the handoffs, it seemed to me that Tyson got started late. The other handoffs were okay, and they should have been able to get through this one, but it was just a lack of practice. Putting Tyson on the relay (and on the anchor) with as little practice as I'm guessing he got seemed to be a poor decision. That being said, dropped batons happen. To everyone, even to A&M at the most inopportune of times, even though they have practiced with each other for 1-2 years. Just sucks to have it happen to both teams here.
