Now is clear that Mike Smith is probably the best coach in the US. I was thinking at him as the best option for 5K and 10K runners, but Colin is clearly a 800/1500 type of guy and Mike has now proved he can coach that kind of athletes, too. If he manages to coach to stardom or close to it a pure 800m guy like Aaron, anyone should consider him as the best option. Sure, there are Ben Thomas, Marcus O'Sullivan, Andy Powell, Vanhoy, Miltenberg, Bonzi, Bryne, Dave Smith, Warhust(and I'm sure I forgot someone else) and many other pretty good options, but what Mike is doing in managing elite prospect without messing it up at altitude is remarkable
