Take a look at this first play in this video.. This video was taken last season and as you can see Pennington throws that ball 50+ yards IN THE AIR for a TD pass to Coles ( it's the first play in the video).

Now please tell me why Pennington can't do that with Ginn ?? Penn threw it from his own 37 yard line and it was caught at the opposing 10 yard line and Coles walked in for a TD..
But you know what? I like the fact that Ginn will have to learn the intricate parts of being a receiver.. Because he just won't rely on his deep route, he will actually learn and become a better all around receiver with Pennington... But if Ginn wants to fly downfield, as you can clearly see in that video, Pennington can get it there-- with accuracy !
