Not the best video but you can't miss this right after the handoff 5:25...

Kenya's 800 man Tangui has been passed by McBride, but Kenyan anchor Cheruiyot is clearly gunning for the pole position. Blankenship basically looks straight to the side at him and waves, as in 'Want the lane? Go, pal.' Cheruiyot explodes seconds later and proceeds to run his ridiculous 51.9 first lap while Blankenship solos a perfect mile to blow Cheruiyot's doors off in the last lap.
Brilliant run by Blankenship, and full credit for some in-the-moment psychology.
