Based on what I know about Lesnar, he's going to stick with his boys.
Having said that, I'd be great to see him train with Mighty Mo. There's a few other guys that fight similarly. Soa Palelei (sp?) comes to mind. I could see those two guys in particular bringing each other up quite a bit. Wrecking machines.
Apparently join dates do matter. 
markKerrSMASH - I just talked to Greg Nelson at training tonight, he's been doing privates with The Academy team here in Minneapolis. A lot of striking.
Striking with who?
He's publicly stated Marty Morgan is on board, I haven't heard him mention Nelson
Based on his new tattoo it's Ido Portal

markKerrSMASH -CaptainWoody -Check Greg Nelsons striking credentials, and then look at their website. But he is back with them the people that he won the most fights with.markKerrSMASH - I just talked to Greg Nelson at training tonight, he's been doing privates with The Academy team here in Minneapolis.

I very much know who Greg Nelson is
Pat would be a huge asset to bring in
Marty Morgan lives 5 minutes from me, my son has done his Iron Mustangs wrestling camp a few years.

Soa and Hunt are friends from AKA Thailand. Doubt he'd help prepare Brock.
