Going from one of the oldest and most out of date facilities in the league to the newest absolutely makes a difference. I don't think we're selling people on a new arena though as much as we're just no longer hampered by a bad one. It's a quality of life issue. If you're going to work in the same building for years and spend a large chunk of your time there, you want it to be clean and inviting. You want comfortable chairs and warm lighting. Maybe people don't actively think about it, but if it's not there you notice.
I don't want to go deeply into the percieved problems with Rondo and Cousins here in yet another unrelated topic, but I will say this: Thibodeau knows Cousins and Gay through Team USA and he knows Rondo from his time in Boston. He's got a better idea than anyone if he could make it work. Any of them could be gone next year or Vlade could bring them all back. That's something for Vlade to discuss with whoever wants the job. And as much as I like Karl Anthony-Towns, he didn't average 27, 11, and 3 this season or make 70 threes or grab 100 steals for the third time in his career. DeMarcus is without a doubt a bigger star right now than anyone on Minnesota's roster. I don't know how we've arrived at a point in time where Cousins is more underrated in his own fanbase than the rest of the league, but any coach worth his salt would kill for an opportunity to "clean up" that mess.
And it counts for something that Rondo outright led a league dominated by high volume scoring guards in assists, was near the top in steals, and shot a very respectable 36.5% from three this season. That's above average at the position. He was very close to becoming the first PG since hall of famer John Stockton to average 12 assists per game. And he was selected to four straight all-defense teams under Thibodeau's tutelage in Boston. At least some of that sounds appealing to me, jackass or no.
Today's perimeter league is tomorrow's bump and grind league. It's just basketball. A 7 foot monster catching the ball 5 feet from the basket is still the most reliable way to put points on the board and that's what you get with Rondo/Cousins.
