I think he may get to this:
(50 indoor):in fact already has a 5.45 wr,made in 100m in berlin)
5.56A (bailey)--> 5.40
(60 indoor):in fact already has a 6.31 wr,made in 100m in berlin)
6.39 (mo greene)--> 6.25
100 meter:
9.58----->9.46
150 meter: (world best 14.35 by him)
14.35---->14.20
200 meter:
19.19---->18.99 ?! (add too 200 indoor)
300 meter:(30.85A michael johnson world best)
30.85A----->30.60 (if he takes it seriously)
400 meters:
43.18---->42,80 (add too 400 indoor)
400 meter hurdles (if he learn to jump hurdles)
46.78----->46,55
4X100:
37.10---->36.85 (being asafa, frater and carter or a 'new beast' on top form) (add too 4x100 indoor)
4X200:
1:18:68 (GB)--->1:18:33 (if he gets a better team or become american) (add too 4x200 indoor)
4x400:
2:54:29-->2:53:86 (if he became american the last years of his career) (add too 4x400 indoor)
Long jump: (based on the last news..)
8.95------->9.16m ?! (add too long jump indoor)
10 world records/world best outdoor + 8 world records/world best indoor before he retires.
I dindt count short hurdles distances (50h,60h,110h..), since he is too big for this events (maybe Im wrong) and triple jump since it is too technical maybe.
could it be achieved?? if you really think about it,he already has 6 of them if you count properly, plus he has lots of potential imo..
any thoughts?
