We high 800 runner can go sub 45 now outside Rudisha?
Off 45xx relay he's a 400/800m runner .
Even if he could get down to 3:32 he's still got more potential at 800m
This is a great point. I think Brazier's definitely got a high ceiling in the 1500m/mile but his shot at a medal lies in the 800m. Even assuming he can run 3:30-3:32 (which in itself is an optimistic prediction; I can't see him running faster than that with his speed orientation), he's not sniffing a medal with that kinda speed with the way the 1500m currently is. On the other hand, in the 800m he's currently in contention to medal or win worlds and even has the WL. Murphy has a very similar set of wheels and range but look what happened when he got too ambitious and tried the 8/15 double at USAs in 2017. If it ain't broke, don't fix it.
