Those of you that played baseball or were in positions to catch the ball in football will understand this more, there are some guys that throw what is called a heavy ball, the trajectory isn't any different but when it gets to you it seems to be heavy and hard. Then there are others that when the ball gets to you it seems as if someone just tossed it almost underhanded, hardly any impact at all. The light ball is easy to one hand and pull out of the air, the heavy ball takes everything you can do to catch it. With a baseball it was like someone adding lead to it, it would hit my mitt and carry through to having my wrist flex. As a shortstop or second basemen it was a lot harder to turn plays because the ball would be harder to control and dig out to throw when turning a double play. In football any thing that isn't in a position to get a secure body behind the ball and to help with the catch with your hand can be a lot more difficult, almost a double clutch to verify you have it.
Wilson throws a easy ball to catch from what I have seen, it's not the heavy ball and it seems to me the receivers have a easy time handleing it, it's not blowing thru their hands and they seem to have a easy time reaching out to pull it in, this would make them confident in the ability to catch it and also able to get RAC's since they don'y have to put their body behind the ball to help them catch it. It is also the type of ball that doesn't get picked off a lot since the ricochet effect of a hard or heavy ball bouncing off their hands is much less.
I don't know if I confused anyone with what I was trying to say, but those that have played and been on the receiving end of both sports know what I am saying, it's a big difference.
