The one thing the stats don't show is how often he was double and triple teamed, creating opportunities for his teamates. This is a form of being productive.
For example, due to the fact that he has shown that he can simply blow by a cb if they play to close, or try to single cover him. Instead of getting torched, defenses would usually have a CB give Ginn a huge cushion as well as rolling their safeties over for deep support. This would open things up for the running game, and guys like Gonzales. This is an example of that speed, explosiveness and talent translating into valuable production. A defense can take anyone out of the game if they choose to, but it is at the expense of leaving others wide open.
A good example is Terrance Newman, is it fair to say that he is not productive because the stats show less interceptions and passes defended due to the fact that QB's would tend to avoid him? I would say it is the highest form of complimient.
This is exactlly the reason I feel Ginn brings the biggest impact to our offense from day one. After he roasts a few CB's on fly patterns, there will be double teams, or else. With Glenn & T.O., somebody is going to get theirs. They will be forced to give Ginn cushion, or roll safety help, this opens up the running game.
As I said before, I really don't care if somebody else likes the same WR as me, but it is hard for me to understand how anybody could fail to see the benefit of having a weapon as dangerous & exciting as Ginn.
Other than C.J. I doubt any other WR earned his stats against as many double & triple teams.
