I think any doubt in Bolt is pretty much unfounded. As long as he doesn't false start (which would itself be very unlikely despite the WC) he will win both 100 and 200 imo.
Even with those odds I would hate to have to support Gatlin.
NBC will air a total of 5,535 hours of Olympic coverage during the London games. That's a little over 230 full days of coverage crammed into two weeks across six networks (NBC, NBC Sports Network, CNBC, MSNBC, Bravo, Telemundo), two specialty channels (for soccer and basketball), a 3D network (for cool-looking 3D stuff) and NBC's website
Probly has more to do with him being 6'5. He's never been particularly great out of the blocks. But yea its not out of the question that its strategic. No reason to risk a dq to win the first 10 meters if ur a near lock to win the race anyway.
