Virtually simultaneous shape of 46.91i, which is worth quite a bit faster outdoors, and 3:59i, with a lot in the tank at the end.
How many have ever had both at the same time, if you factor in that in that mile he probably could have run mid to low 3:50s with competition? Just taking the times at face value, you might say that plenty of milers and 800m runners could do those things the same season. If you consider it likely that he is ready right now to run sub 46 FAT outdoors and maybe low 45 or high 44 in May-June outdoors, since indoor turns slow down the 400m quite a bit and no one is in his best shape in January, and then consider that he closed very easy in the mile, we have a talent here who rates with Jim Ryun, Sebastian Coe, and only a few other milers in terms of simultaneous 400/mile shape. Clayton Murphy might well slot in there as well with his 45.4 4x400 split and 3:36 1500m.
