Ray isn't a bad hockey analyst when he isn't on MSG doing a game. In fact, he used to say it how it was when Neale was RJ's right hand man. Now, he's just a Sabres puppet. He must of been told, if he agrees to the promotion, he will need to become a propaganda machine for the television side. He's said some of the most redic things so far this season.
I think Rob isn't comfortable enough in his position to feel that he can criticize the team. Who knows - they may have even expressly told him not to be negative. However, I did notice the last 2 games he was a little more honest about pointing out some of their mistakes and short-comings. I always liked Rayzor as a player, so I'm probably willing to cut him more slack than most. I think he will improve as he gets more comfortable.
That all having been said, he's barely good enough to carry Brian Duff's luggage.
