Centro is quite possibly the most boring US 1500m elite man of the last 15 years. What appeal does he possibly have to offer us? None.
Webb- fastest US high schooler ever. Was the great US hope for the mile for years. You hate him or love him but you had to admit he was entertaining.
Leo- been around for a long time. 2x NCAA champ who has made a great transition to the elite circuit. He races with courage and you never know which Leo you're going to get, the good or the bad, with him, which to me is exciting.
Lopez- has the "lost boy" appeal. He is always fun to watch just because it seems like people count him out a lot but he is always there in the hunt.
Rupp- similar to Webb. Record breaker as a high schooler who is now kind of the next white hope for 5k-10k. You either love him or hate him but he is always there making headlines.
Solinsky- raced with fire and passion. He's on the comeback trail now which is always fun to watch with any runner.
Centro races with no heart and shows no emotion. He's a white dude who is damn good but there is nothing there that makes me interested in rooting for him or following him. Every time I see results from him it's just like 'meh' when with most other Americans it's much different. I just don't see anything fun or exciting from him, which in my opinion is what this sport needs.
