No, it was tame, and the first was never a yellow to start with, commentator got a few things right in the game, Arsenal got away with several tackles that were pretty much clear yellows then Sidwell got one for almost nothing on Santi, had he been sent off, it would have been ridiculous. Ramsey however did two cynical tackles, both shirt pulls with a bit of leg contact in the mix, both times stopping breaks.
Sidwell wouldn't have been unlucky to get sent off, it would be flat out wrong, Ramsey was pretty lucky to not get sent off.
EDIT:- it wasn't a bad tempered game and Ramsey didn't do nasty tackles, but both would be deemed your classic yellow because it was cynical/stopping a break situation. Ramsey wasn't actually lucky to not get sent off, people are rarely sent off for just two yellow card worthy tackles, however he could have been sent off rather easily, Sidwell didn't even deserve one yellow card.
