Perhaps not too relevant to the question of what he could have run over the weekend, but I do recall the first time I ever raced Potts happened to be a memorable 5k. Carlsbad 5000, 2003 I was 22... I had done Oceanside 70.3 the week before and the short-course National Team had an ITU camp in Chula Vista, so those guys came up and ran. I was staying with my brother as he was playing college soccer in SoCal, so I drove down to to Carlsbad from LA that morning deciding to give it a go. We were in the U-29 division with about 3000 or so people, this race separates into grouped running "waves" all day. I have no running background but was into soccer/basketball/tennis growing up, so always had some speed. I went out way too fast as always, but it was sea level & this is the course to set your PR on I'd heard! Through mile one I was leading our wave in 4:28, through mile 2 I was in 3rd in 9:15, and in the last mile I fell to pieces and finished I believe 7th in 15:12. Potts came by me in the finishing straight absolutely flying in full Michigan cross-country gear, he had long hair in a ponytail and looked like a bad dude, like the lead actor in that old TV show The Highlander. I remember Bob Babbit was on the mike and was super-excited about the Michigan swimmer-turned-triathlete finishing up 3rd. I will say his kick was impressive, but I was just trying to get to the line having blown to pieces at that point! It was cool and gives you an idea of what our US Team ITU guys could do at the time in a 5k in that era, I doubt they were tapered, or put a lot into this event, I didn't either. I stumbled home in the last 800 being passed by Potts, Fretta, and Fleischman in sight of the finish, Potts went 14:51 that day.
Here's the results link, there are some weird times in there (Nobody ran 11 minutes) but you may recognize some names and get the idea.
