It now looks more and more like LeBron will stay with Cleveland, and Bosh may end up there too. I'm not sure how much that will help Cleveland though. Even with Bosh, I just don't see them in The Finals.
As for the Knicks: their acquisition of Amare now makes them look foolish and very desperate, which sucks imo. I really wanted to see the Knicks get somewhere, I think getting Amare isn't going to change anything.
Imo, the postseason in this new decade is starting off with what the experienced veteran teams like LA and BOS have left. I think this Boston vs LA rivalry has a couple of more face-off's to go yet before we see a generation changeover to Cleveland and other teams.
