I say any leg but 3rd, here is why
Wilson is a young kid who will be running against much bigger grown men
Leg 1 - in his own lane the entire way does not get mixed up with the bigger bodies
Leg 2 - gets the baton in his own lane does not have to deal with the possible pushing and shoving in the exchange
Leg 3 - this could be bad. Young kid getting bounced around by bigger more powerful guys in the exchange
Leg 4 -hopefully usa has a big lead and he can just run free and clear
Of course I expect he will only run the trials and not the final
What do you think
