There are a few teams that just missed inclusion in this list.
If you think the Brooklyn Nets are already contenders, their acquisitions of All-Star shooting guard Joe Johnson and backup point guard C.J. Watson will certainly take them a step further. The fact remains, though, that a team should probably have to prove it can make the playoffs before we call it a "contender."
If you think the Dallas Mavericks still deserve mention among the Western Conference elite, then a thoroughly rebuilt roster that added O.J. Mayo, Darren Collison, Chris Kaman and Elton Brand would surely qualify as having made a big splash.
At this point, though, there's just no telling what will happen to this team. It hardly resembles last year's squad.
The New York Knicks get the nod here given how impressive this team looked under Mike Woodson toward the end of last season.
And, they would have looked better against the Miami Heat in that first round if not for injuries to Jeremy Lin and Iman Shumpert.
Though the organization won't fully make up for the loss of Lin with a platoon of Jason Kidd and Raymond Felton, adding Kidd to the mix will functionally add another coach to the bench.
The more important moves were relatively quiet ones. Adding center Marcus Camby and swingman Ronnie Brewer to the bench will make New York a significantly better defensive team. Losing Landry Fields will hurt a bit, but he wasn't worth what the Toronto Raptors were willing to pay him.
Given the Knicks' lack of cap flexibility, this team did a nice job of putting the roster in a position to succeed.
