Geoghegan needs to run a couple seconds faster to be considered. Ulrey showed loads of potential before joining up. Unfortunately, he was probably used up as training fodder, as most NCAA athletes would probably be if they joined with the NOP. Based on that, he shouldn't join up even if he was given the chance.
If he got a few seconds faster on his own, then why would he even need to join NOP? Clearly then his training system would be just fine.
