He is already better than everyone in the Tinman group. If there had been a track season, he would've been a 13:20 / 28:00 guy by the end of the summer. Being the best guy in your group is not in and of itself bad, but for a new pro you need someone (teammate or coach) who has been to the top of the mountain and can teach you how to get there. Drew Hunter is essentially a peer, so doesn't really fill the grizzled veteran role.
Klecker is mature and will hold himself accountable, so doesn't need a coach there every day. I could see Ritzenhein coming up to Boulder every so often to check in , or Klecker going to Michigan for some sharpening (similar to what Parker Stinson has done). Ritzenhein knows the value of altitude so, for athletes with the means, I'd think he would endorse a permanent home up high.
This is of course just speculation on the internet (aka jerking off), but given similar backgrounds - growing up in the North, CU, ultimately 10km-marathon skill sets - this would be a great situation for Klecker. The kid seems to have a good head on his shoulders so he'll be fine wherever he ends up.
