Did you happen to see the salaverry fight? Riggs was doing a great job till he got caught with an up kick that basically knocked him out and he fell into a triangle. Ivan Salavery is a top fighter imo.
Riggs has the skill and the tools he just never seems to put it together. He has moved over to MFS and he trains with Jeremy Horn's group in Utah. He should be putting it all together in the near future and making a pretty good run. Riggs is solid and only like 23 or 24 he will be around for a long time.
That being said I hate to say but Diego wins by GnP
