Jseven,
I would add the 400 to the adventages that Eaton got over Sebrle.
I believe that the WR is in his reach today, but he will need the perfect competition.
For example:
10.35, 7.90, 14.80, 2.08, 46.1, 13.45, 46.00, 5.20, 58.00, 4:20.00
are all within his current form and will give him 9,030 WR.
But, I also believed in the past that Clay (and Hardee) can break this record and proven (so far) wrong. So having the potential is obviously not enough.
