I hopped on Twitter several moments ago only to see @nfl retweet a clip from @nflfilms of the Mario Manningham catch from SB XLVI. Belichick challenged the play, and rightfully so. The refs ruled the play as a catch, stating Manningham caught the ball and maintained possession. But did he though? I went and looked back at the video, slowed it down at the slowest setting. His feet dragged behind him as he went out of bounds. After he caught the ball, he got his right foot down.
