I had the same problem with the league site last night. Thought it was just some script problem.
As far as the game - I agree that the tackle windows are way too small. Same situation as Ram, I sniffed out a screen and I'm standing right over the guy, no dice. What's worse is that the AI controlled players get juked out of their shoes with a simple change of direction.
Secondly, the XP system is worse than last year IMO. It is far too easy to get a guy who is a complete slug in one or two categories and turn him around in a couple of weeks since the category upgrades are so fucking cheap until you get to around 80. We're all going to have teams that are even more ridiculous than last year by mid next season.
As far as the injuries, I've had a ton of them too, but they haven't been too severe. I don't think it's a big deal if it's like that, but if it ends up with 3-5 guys per team out for serious time by the end of week 3 then maybe we should look at it.
