Some of you guys are missing the point about the standing and/or haven't been paying attention these last few years. Sure, maybe it started as cheering or team unity, but it has taken on a specific agenda by the players these last few years in opposing arenas. Very rarely is the issue with the home team standing and obstructing fans' view. It is the visiting team that has decided purposely to counter hostile environments and fans of opposing teams by standing in their way.
I have seats not far from the visitors bench at the Garden, and although not affected myself, I have witnessed this behavior many times. The players are not standing simply to cheer or support their team, they are purposefully taunting opposing fans, often turning and smiling at those whose body language, and sometimes words, have expressed disappointment at having their view blocked.
I have thought the last few years that the league should do something about this, so I applaud this action. Regardless of the price of the seats, the league rightly recognized this act of protest of players, under the guise of team support, for what it is. They can still jump up and cheer on a play or teammate, they just can't stand for the whole time which was being done almost solely to p--- off the fans and get some payback in a hostile arena. Since fans are the ones paying to keep the league afloat, the league should take steps to curb this behavior.
