Didn't see the play, but I'm not complaining (started Mason). I wouldn't be surprised though if it was a bad call. I know most people, especially players, will rant (at least on their sidelines and locker rooms) about bad calls, but from what I observed last season and this week I hold firm that referees have been getting constantly worse.
Let's not even get into the fines and penalties for hitting WRs too hard (its football and they have pads) that plagued last season. Let's forget for a moment about the absolute failure to function at an acceptable level that nearly resulted in a brawl during the Giant vs. 49ers playoff game. Let's just exaimine this week.
We have the disputed Mason TD, which I will let others comments stand for having not seen the play myself yet. There's also a ridiculous call I couldn't believe (especially after seeing the replay) made during the Giant/Rams game. With the score 13-23, the Giants pressed up instead their own 10 yard line, and a hit from the Rams defense pops the ball loose. A diving Ram recovers the ball (about 2 yards shy of the goal line, and the play is over. My only guess as to why the Giants kept the ball is that the refs ruled lack of possession. However, the Giants ball-carrier had enough control to run without bobbling the ball, and that why the Rams didn't challenge this game turning call is beyond me.
Maybe I'm just bitter about refs in general, as none of the examples I can think of directly involve my favorite NFL team. However, I do really think the coaches and players of the league need to do something about the general quality of officiating being done. Bring up complaint after complaint to the comissioner, and eventually he'll get the hint. Especially this hitting too hard nonsense. No player should have to be worried about losing a week's pay because he played the game the way he was supposed to.
