I'll say it again, I don't think he trusts the Cowboys training staff any longer. I have been saying it over and over and over.
When the NFLPA released their team grades based on their union members votes, below is what was stated about the Cowboys who ranked 12th overall for team grade.
"The major issue in Dallas, based on the responses, is centered around the training room. The players feel like they are very understaffed in this department, and it is difficult to get the necessary preparation and treatment to perform at their best. Only 62% of the players feel like they get an adequate amount of one-on-one treatment time, which ranks 30th in the NFL. The other issue mentioned was that the players feel the training room lacks basic equipment that you would expect to be standard in any other training facility."
He is not the only Cowboys player or recent former Cowboys player with those feelings.
