Looking at those video, I think DS and TS are too high. He never run with the ball, just play in one touch, his role his to intercept ball, then he just give a short passes, simple defensive works. And when he run a bit with the ball he just looks like a white DS or low green to me. Also TS doesn't look to need to be on yellow, he mostly use his burst and then will tackle every time the opponents continue his run on a long distance. It looks like he can follow him so tackle after a burst to be near of the opponents to tackle the ball and not the leg^^.
Looks like also he use mostly short passes, doesn't seems confident with the long ones. Agression is more a 60', just cosmetic but with a good resp he can be too much offensive in game if you give him a decent agression.
He's also a WFF 4, he looks like he has no body turn as he use his right foot for all, control, passes and turn, even in a bad positions wich need the use of the left.
By the way speaking about his body turn, not sure on the yellow value. Not sure also on yellow BC from those video.
I'm sure you know him more than me but I just would like to post my view on this video.
They have eyes but cannot see; they have ears, but cannot hear; they have tongues, but cannot speak. They are like cattle.
