Here's the 10,000 top-15 list:
1 26:17.53 Kenenisa BEKELE
2 26:22.75 Haile GEBRSELASSIE
3 26:27.85 Paul TERGAT
4 26:30.03 Nicholas KEMBOI
5 26:30.74 Abebe DINKESA
6 26:35.63 Micah Kipkemboi KOGO
7 26:36.26 Paul KOECH
8 26:37.25 Zersenay TADESE
9 26:38.08 Salah HISSOU
10 26:38.76 Ahmad Hassan ABDULLAH
11 26:39.69 Sileshi SIHINE
12 26:39.77 Boniface Toroitich KIPROP
13 26:41.75 Samuel Kamau WANJIRU
14 26:43.98 Lucas Kimeli ROTICH
15 26:44.36 Galen RUPP
It's really not that spread out. I could see if Bekele was running closer to 26 flat that, then there'd be a considerable gap, but he's "only" 20 seconds faster than Tadese at #8 in a 6.2 mile race.
Here's what the 5 looks like - only a 10 second gap between Bekele and #7:
1 12:37.35 Kenenisa BEKELE
2 12:39.36 Haile GEBRSELASSIE
3 12:39.74 Daniel KOMEN
4 12:46.53 Eliud KIPCHOGE
5 12:46.81 Dejen GEBREMESKEL
6 12:47.04 Sileshi SIHINE
7 12:47.53 Hagos GEBRHIWET
8 12:48.64 Isiah Kiplangat KOECH
9 12:48.66 Isaac Kiprono SONGOK
10 12:48.77 Yenew ALAMIREW
11 12:48.81 Saif Saaeed SHAHEEN
12 12:49.04 Thomas Pkemei LONGOSIWA
13 12:49.28 Brahim LAHLAFI
14 12:49.50 John KIPKOECH
15 12:49.71 Mohammed MOURHIT*
I'd also agree with a previous post that both Geb and Komen, in their prime, would've given Bekele a decent run.
