Just to make my bias clear - I'm a Matt Moore guy. Nothing against Garrard, won't be upset if Garrard starts, but Moore is younger, has a less worrisome injury history, and played well despite no offseason reps with the Dolphins.
So when I heard he was a bad guy at practice, I thought that he occasionally overthrew guys on routes he usually could hit in game.
Or maybe got a delay of game occasionally while overthinking.
"4th down, 18 yards to go -- Matt Moore spikes the ball. (Can't believe he did that on fourth down.)"
