The tackling debate is an interesting one, its fascinating hearing peoples take on incidents like the NGog one. I've seen alot of those kinds of challenges and players hurdling them to then go down and it always just seems to be one rule for their own sides players and another for the oppositions. Divings become such an epidemic in the game and you rarely see people keep their opinions consistent for every side in the league and in the sport as a whole too.
As much as people complain about witch hunts (which clearly do exist) some of us as fans, play straight into them just as much as the media. The whole reputation thing definitely comes into play in this and certain players for opposition sides wouldn't get the benefit of the doubt for things others would. Apply this hurdling a challenge debate to a number of players considered 'divers' across the coarse of a season and peoples judgement of the laws of the game and the challenges in question will vary massively. The only exception i can maybe have a little understanding for is when it comes to a fierce rivalry, when it comes to sides the majority of a teams fanbase have a strong dislike for, the judgement of a foul or dive seems to change due to the reputation of an entire side as cheats and the magnitude of the match being played.
I dont remember the NGog incident incredibly well, i remember most of the detail from it but the most important factor is something i don't, the main two issues for me in the type of challenge in question are A. could the player have continued his move rather than going to ground and B. how reckless and dangerous was the challenge. Obviously there are grey areas and its not as black and white as these two factors alone but i still feel these are the main two factors.
In terms of Suarez i feel he has changed his approach to the game a little, whether its down to a change of position and him occupying slightly differing areas of the field or something else i'm not completely sure and the fact i've missed a few of our games this season due to work most definitely plays a part but i can't remember the last time i saw him receive the ball with his back to goal and roll his marker to take them on. He still gets fouled a ridiculous amount but it seems to be in different situations this season, i feel the most common situation in which he was fouled before was the back to goal one, time and again we would see players steam in and clatter into the back of him, drag him by his shirt as he took the ball past them on either side or kick at his ankles as he took them on. We don't seem to see him in this type of situation quite as much anymore
