I looked at the list of times for the meet and Lemaitre didn't come last as I initially thought. This meet was a level above an all comers meet and had 11 flat participants who were NCAA athletes.
I hope he isn't desperate to hang around in track as track has had a similar history to boxing or the former Big 4 league players kicking around low paying minor leagues desperately chasing pay cheques. Ben Johnson did this for years until he was exposed as a 11 flat shot runner and a few years ago Walter Dix was running times similar to what Lemaitre was running this weekend.
