That may be a part of it but I think Roy has done more to destroy his own position as "The Guy" than anyone else has done to take it away.
To be the leader you must have the respect of those you lead. Roy can't produce as he has in the past and yet he is blaming those who CAN produce for his own shortcomings. Not very good in the "Win friends and influence teammates" area.
I think when Roy was initially hobbling and hurt by the knee, people give him slack, including teammates. However, when he still claims to be able to lead and produce when he obviously can't and then deflects blame on those he is supposed to lead can very quickly alienate those whom you are supposed to lead.
Players aren't dumb. Who is producing on the team? Matthews. Miller. LMA (with quite the WOW the past couple games).
What has Roy become? Bear with me here - he has become Sergio. Many here, myself included, wanted Sergio to play more because we'd see the occasional flash of brilliance and think "he's the next Nash!". Roy has been on the cusp of greatness but now he is reduced to Sergio level. We occasionally see flashes of greatness but more often than not, we are starting to cringe when he is playing. I was honestly glad to see the report that he was out three games. With what I've seen of him lately and his attitude, I just don't care anymore.
So....Is it LMA's team. Oh yeah.......but only if he is willing to take it. If he can consistently perform at leadership level, this team is his.
Gramps...
