A Nash player (I forget who) weighed in on this, he said that if Gief plays the ground game he’ll take even more damage. I also find myself jumping a lot more against Nash than in other matchups.
As for Necalli, he gets oki off of everything and forward dash into cr. fw. (?) is very hard to deal with. He can alternate between normal jump ins and divekicks to bait Lariat. His attack is very diverse; he hits hard, is very mobile, has a command grab, an overhead and possibly the best V-trigger in the game. From afar he obviously has Seismo. His combo ability is great too, you’re always only one quick dash + cr. fw. away from eating a combo or a CA.
On another note, does anyone have some general advice against Kolin? A Diamond Kolin I play against knows the matchup very well and he has a hit-'n-run style that feels similar to S1 Nash. Am I blatantly overlooking something or is this - yet again - an awful matchup?
