I watched 1 fight so far as far as research goes. Here's some notes from the Carniero/Niinimaki fight.
Renato Carneiro
Bio
5'11, is tall for FW
-Trains in Brazil at Constrictor Team, with Rani Yahya, Francisco Trinaldo, and a few other undefeated guys. Seems like a solid camp. Not sure how good his wrestling will become.
-Did not have an easy path to the UFC apparently, most or all regional opponents were winning records.
-UFC debut against Niinimaki, won by submission. Niinimaki has been submitted 5x in his career, and was submitted by choke in his last 3 fights (Skelly, Backstrom, Caneiro).
Physical
-Probably not a ton of strength. More of a speed/cardio fighter.
-Cardio seemed fine in round 2.
Striking
-Very good kicks. High, low, mid kicks. Attempted a spinning kick.
-Very good hand speed.
-Seems to utilize a reach advantage well vs Niinimaki.
-Good technical offense.
-Has eaten some leg kicks. Has checked some.
-Good at using reach and distance.
-Stays on the offensive, controls the center of the cage.
-Good at avoiding strikes, but does seem susceptible to punches at times.
-Catches kicks.
-Good counter striker.
-Good killer instinct.
-Not a ton of punching power, but kicks hard.
-Didn't see clinch work
Grappling
-Started training in elementary school in Judo. Then progressed into BJJ.
-Ground seems to be strength, but striking is solid.
-Wasted no time jumping on a hurt opponent.
-Immediately passed, then during a scramble took the back and good body triangle. Solid RNC vs a decent grappler who was hurt.
-Has a judo background, didn't get to see it.
-Didn't see much wrestling or any GnP in the fight.
