We know you want attention but you post such nonsense. Nobody can take you seriously.
Why are those predictions so far fetched? He just ran 3:38 in his first race at the distance with his focus elsewhere. At the very least one can conjecture that DB can run a lot faster. Would you bet $1000 he can't go 3:32?
Spend a bit of time reviewing IAAF 800m & 1500m historic results. I believe 136 men worldwide have raced sub-1:44 800m. I believe 18 or so U.S. men have raced sub-1:44 800m. Now review how few U.S. sub-1:44 men have also raced sub-3:35 1500m. A thousand dollar bet I would more than likely win regarding Brazier and sub-3:32 1500m.
