That was realistically the best scenario that could actually have happened for his last race.
Get the baton in the lead and win- would have taken too much of a lead and why USA put Gatlin in the two hole, which was their demise too.
Get the baton in the lead and blow the lead- whoa, not a good look to retire on
Get the baton trailing and power to a win- good luck with that, Jimmy
Get the baton trailing hold position and get another bronze- too vanilla, snoozer, plus with GB's crazy win, less time to adore Usain.
Get the baton trailing and fade out of the medals- Japan was a bit back, might not have caught Bolt, but if that thought popped into Bolt's head...
Get the baton trailing and fall to track like a sack of Micheal Johnson's potatoes- winner! everyone feels sorry for Bolt. Press barely acknowledges real winners, all camera on Bolt.
