Agreed with your points above, But as far as tackling goes ,the FA should show a film of ross to young players starting, out saying if you tackle like this lad you will get your leg broken (twice).
I actually think he's told not to tackle as well mate which in turn means he goes into tackles more half arsed and is more liable to be injured.
I never seen the tackle that Andre Wisdom dome to give him the double break so can't be sure if it was a full blown tackle or just an impact where both players go for the ball.
One things for sure though, mentally Ross looks like a kitten when it comes to challenging a 50/50 ball or going in for a header. I don't like comparing players but if you look at the likes of Aguero, Sanchez, Rooney, Suarez - they hound the opposition into mistakes so the turn over of the ball is quicker. Ross simply let's people stroll past him likes it's a game in the park on a Sunday
If he could add that aggression to his game ( whether he has the stamina to do this is a different matter ) it would certainly add to his overall contribution.
