Not even big richo could argue weitering was doing anything other than blocking Tom.
No doubt he is trying to keep him from the ball but I think you can argue either way about the free kick.
A still shot really doesn't tell you anything, when you look at the full replay they are both engaged from the time the ball is kicked, it's not like Weitering moves to get into his path.
Weitering is allowed to exist and engage his opponent, he doesn't have to say 'sorry Tom, the ball has gone that side, I'll step aside and let you past', so the free kick really comes back to is he making a realistic attempt to contest the ball?
If his team mate wasn't there would he have pushed off Lynch to try and mark or spoil the ball? I think you could make both cases equally well, which is why these decisions are very hard.
What I would say is the Taranto thread has a post about him executing a block on Weitering that helps Lynch take a mark to tie up the game so all the woe is us stuff is complete nonsense, as usual.
