I'm going to pick Tom Nolan here. I think technique wise, they are equal with Charlie having better defense, but Tom is long, lean, and durable. Only actual concern is the leg kicks, but Tom moves forward too much for Charlie to plant and throw. So Nolan is the pick, the odds are solid and I like the round over as well.

Tom Nolan

Tom Nolan is a long and lean striker. He is accurate and technical, but has no problem getting into a brawl. Outside of his lone loss, he has a solid chin as well. I have seen him in more than one fight eat more than one overhand just to keep coming forward. He has lots of pressure, lots of volume, tons of power, but not much striking defense or takedown defense. He is coming off the decision win Viachslav Borshev where a well timed takedown seemed to lock it up.

Charlie Campbell

Charlie Campbell is a technical striker who likes to pick his shots and use accuracy instead of coming forward with large combinations. He can be a bit hittable because his hands are low, but he has nice leg kicks, great takedown defense and is very busy on top. He has solid volume but can slow as the fight goes on. He is coming off the decision win over Trevor Peek where it was clear Trevor is not a skilled fighter.
