He actually said as to why RS didn't practice, " you'll have to ask him, I have not talked to him about it."
Asked what he accomplished by standing out there at practice..."you would have to ask him."
Not sure what else you expect him to say, he is not speculate on Smith's motives or stick words in Smith's mouth, nor should he.
As for the Bears PR department not making RS available to the press, that is 100% Roquan not wanting to talk to the press. I am sure he is aware they want to talk to him and they have presented to him that the press wants to talk to him and he wants nothing to do with that right now. If he asked the Bears to talk to the press even though he didn't practice, they would surely oblige. Could you imagine the shit storm if the Bears tried to impose a gag order on him?
Plus, if he wants to answer any of their questions, there is nothing stopping him from calling his own press conference. I mean he has already said the Bears don't value him, are trying to take advantage of him, are negotiating in bad faith, and wants to be traded. It's not like he is afraid to say something bad about Poles or the team.
Basically you have a coach that isn't going to speculate about a players motivation that he has not talked to and a player that, other than putting out a crafted statement, has no interest communicating with the press.
