Renny Waldron (Eric Jenkins' first coach at Northeastern) was also a mid 26 8k runner. So by your logic once Jenkins gets a real coach who used to be fast, he'll be running sub 13 by March. Is that what you're saying? Or am I confused?
There are a lot of reasons that a guy like Eric Jenkins runs fast. Two of those reasons are the work of his two coaches. I guess some people have trouble understanding that.
