So I'm digging around D League sites like Ridiculous Upside trying to figure out who Demps could be going after and I run across this article about DLeague bigs the Hawks should go after since they didn't get Shaq. LINK
One of the guys that seemed to potentially fit what we are looking for was:
Pops Mensah-Bonsu - I'm going to let Mark Deeks from ShamSports explain this one: "Mensah-Bonsu always sports a great rebounding rate, can get some points through sheer hustle and athleticism, and has a good handle for a power forward. He is prone to the occasional delusion of grandeur, but he causes turnovers, wins possessions, scores some baskets, grabs some rebounds, blocks some shots, runs the bejeezus out of the floor, and is disruptive around the basket. No team can have enough of that."
I start doing a little more looking on Pops and he's going to be signing with a team this week that according to his agent is "not in northwest division. Happy 4 Pops he deserves it after huge summer" LINK
Obviously that only narrows it down to 25 teams, but he looks like a 6'9 hustle guy, Indy was allegedly never serious about Amundson (didn't have roster space), which means I think there's a good chance Demps just found his Mustafa Shakur for the front court.
