I think it is very likely that he will be well under 28 minutes for 10k this summer based on that 8k opener (roughly 28:30 pace for 10k). Only 8 athletes broke 28 in 2019 for USA and only 8 did so in 2020 as well.
Combining the two years here is a comprehensive ranking list
1. Lopez Lomong 27:04
2. Eric Jenkins 27:22
3. Shadrack Kipchirchir 27:24
4. Kirubel Erassa 27:32
5. Leonard Korir 27:34
6. Joe Klecker 27:35
8. Hillary Bor 27:38
9. Robert Brandt 27:39
10. Paul Chelimo 27:43
Obviously its a long shot to say he has any chance with this group ahead of him, but if one or two of the top runners is off or doesn't compete in the 10k he could be in the hunt for a spot. A 27:45 at the Oly Trials might be fast enough if the race is more tactical.
At the very least I think there is a possibility of seeing him running in the front pack for most of the race which would be really exciting.
