Watch the replay , Tree tried to flow into at least one of the big runs , and couldn't get through the trash even running laterally .
Cowboys blocker just shaded him with a side of his body ,, lane open.
So if T.J. cant get there and Tree is blocked that's it ,,
The corners have to chase or Alexander has to come across field ,
they are going to have to pinch on DL or offset or something across the DL or the LB's sets to avoid run attacks to the right or maybe even strait dives to the right ,
I'm assuming Hayes can stop some of the problem and maybe both DT's including Donald can fight thru some of this but Tree is going to have to hold up too many times ..
That's a worry against a big FB or guard . getting to second level ..
