He's probably sending them across the middle a lot and they are dropping the passes because they a getting blasted. Jackson and Macklin aren't that great in traffic. .You won't see many wide open drops with the catching at 45 so I know he's sending them in traffic a lot..
I'm not sure why Jackson is getting hurt.It's probably the same issue with the drop passes. He's laying them out to dry across the middle a lot and they are getting punished. He should be using Jackson in space.
To me it sounds like he needs to get in the lab a little bit and work on some things. The bad thing about playing with other people is that everyone isn't always on the same level and you are going to get a few out the group who have issues all the time..
Which set are y'all using?
