The general consensus i get from most DC/Jones threads is that Cormier is going to wreck Jones, i think this is due to Cormier used to fighting at HW and also him being an olympic wrestler. Honestly though i don't see it that way, i see Jones outworking DC on the feet, picking him apart from range having more than 10 inch in reach advantage, Cormier is going to have a hard time getting inside and when he does he has to deal with elbows and Jones' clinch game and wrestling ain't no joke either.
It's easy to pick the bigger and stronger guy with better wrestling credentials, but you got to remember this is MMA, and as a MMArtist Jones is a much more well-rounded fighter.
The clinch game in this one is going to be interesting, if DC can control the clinch and get Jones down he may well win this, but if he struggles in the clinch i see Jones winning a comfortable UD. If DC wants to strike, i see Jones winning a UD too.
