I noticed a Tom of contact with receivers well past 5 yards. Colston looked like he was getting mugged his whole route, not just 5 yard. Then another 3rd down play ended when defender came up Lance Moores back to knock ball away.
I didn't see a difference between that play and the play that Greer was called for pass interference, but that play on Lance wasn't called for pass interference. I don't get it.
