Maybe you are missing the point. Many have drawn their conclusions despite the stats. They would rather not talk about the stats at all but instead point to some media members comments as fact. What exactly did Joyner say? Did he say Roy is the only strong safety with coverage problems? Did he say he was the worst? Or did he just say that Roy has coverage problems (which every strong safety has)?
The statement of Joyner, if quoted correctly, was that Roy Williams is not over-rated because his coverage problems
are already acknowledged. So is Joyner listening to the media homers as well?
My point is, yes, they have given innocent answers to direct questions, but does that mean they are concerned? Did Jones say that he is always out of position or just that he had gotten out of position a couple times? Did he specifically say that his play has declined or regressed?
He was making a general statement and he isn't going to flat-out say he stunk it up last year, considering he is a Cowboy. He also said that the horse-collar rule impacted his play, but he has ever reason to believe he can adjust provided he puts in the effort. And Jerry further said that the reason he has to resort to horse-collaring individuals is because of his technique and position, so he needs to work on these things. Among issues related to positioning, Jerry said he needs to work more on his anticipation. He plays from behind resulting in some of the problems.
So when Roy-bashers talk about Roy not being able to tackle anymore and whiffing on tackles, while it may be exxaggerated, it certainly has a ring of truth to it.
Is it possible that they understood that he had a couple hiccups last year but it is something that every other player in the NFL goes through from time to time? I'm sure Roy isn't the first player that has gotten out of position, had a down year or two, taken a bad angle, whiffed on a tackle etc.
It seems to me, many fans are making this more than the team thinks it is.
Of course he isn't the first player. But the fact is, you only make statements like that when it happens more than normal.
