Don Walker has a story out on JS Online that states that Heb Kohl is willing to chip in for a new arena in order to keep the Bucks in Milwaukee. Not too many owners will put up their own cash for something they won't own, but for Kohl to do this in order to keep the team here, well, maybe he's not the horrible owner that people think he is.
My favorite line of the story is where, when asked about the chance of the team staying in Milwaukee without a new arena, Kohl said the league would say "the chance are not robust".
