So, let's speculate on his character...
Ok, so everyone is assuming Sunspot (don't we already have enough "strong guys" on these teams - Colossus, Beast, Warpath?). Yes, he matches the look (not the age), so it's an option...
He could be a bad guy and maybe playing Avalanche (similar in look to the cartoon version)...
He could be Rictor (haven't seen anyone else post that yet...).
Or maybe, just maybe, he isn't playing a Mexican character...
Here is one that I've been speculating on since I have the idea of BooBoo as Warpath )though would love to see him as Forge)...
Maybe Adan is playing Warpath?
