Official PBs of 1:47.65/3:34.56/7:37i/12:57i/26:52. Pretty sure the normal picks are:
Rupp - 1:49/3:34.1/8:07i/12:58/26:44/59:47/2:06:07 - Faster 1500, 3k, 10k, half marathon and marathon. Worse at 800 and 5k.
Lagat - 3:26 or 3:29/8:09i/12:53/27:48r/62:00 - Way better at the mile lol, faster at 3k, faster at 5k, definitely not better above 5k.
I think Nico has better range than either of them. I can already hear you old people saying "bUt LaGaT wAs a DoUbLe wOrLd cHaMpiOn aNd rUPp goT siLvEr aNd bRoNzE", and while that is true, it's also true that Nico is 21 and already basically better than Rupp. Put Nico in a 3:29 race and he runs 3:31 or faster. Put him in a 12:40 race and he runs 12:45. Put him in a 26:30 race and he runs 26:30.
If you think this comparison is crazy, it'll make more sense after Nico medals this summer.
