This is how I rate them currently in the 100m:
1/Gemeli - obvious #1. Ran sub-10 last season.
2/Kilty - World and Euro Champ in the 60m. Has been running longer races to improve his finishing speed.
3/Teeters - Ran 9.95 last year with 2.6 wind. Runs consistent, good times at 60m and 100m.
4/Lemaitre - immensely talented, woefully trained and conditioned. Still manages to perform decently once or twice/season.
5/Guilyev - ran 19.88 200m last season. Rarely runs 100m and has a terrible start.
6/Reus - runs well in German meets, but not internationally.
I can see an argument for Kilty and Teeters swapping spots, but Kilty has much more experience and especially championship experience than Teeters.
I can also see an argument for Guilyev and Reus swapping spots, but Guilyev is a more proven performer recently than Reus.
So here's how we ended up in 2016 vs. early year speculation.
1/ Gemili - Focused on the 200m and ranked 3rd in the world. Best 100m time was 10.11/19.97.
2/ Kilty - ran 10.01 at a small meet, but generally did not meet expectations
3/ Teeters - ran 10.00 in the heats of the Olympic Trails, but overall not as good a season as 2015.
4/ Lemaitre - finally pulled himself together to win a Bronze medal at the Olympics in the 200m. Ran 10.07 in the semis at the Olympics, and 20.01 in the 200m.
5/ Guilyev - ran 10.07 at the European Championships in a semi-final. 20.09 at the Olympics.
6/ Reus - had some great times in Germany including a 10.01. Choked as usual once he set foot outside of Germany. 20.39 in the 200m.
Bruno Hortelano of Spain was the new face on the scene. Ran 10.06 NR in the 100m and 20.12 NR in the 2oom.
