Let's be real here folks. Rondo is a very nice player and one of the better PG's in the league. He has a lot of areas where he is best in the league, but a few where he really struggles. He is by no means a complete PG who would be considered an all-time great. That being said, he is a nice trading chip to build a contender. Let's not forget the Champions of the past years and who led their teams:
Nowitzki, Kobe, Pierce, Duncan, Wade, Shaq/Kobe, Jordan, Hakeem, Magic, Bird, Kareem, etc...
The only PG that arguably led their team to a Championship, because I don't think Magic really counts at the PG spot, is Isaiah Thomas. Rondo is no Isaiah Thomas. He doesn't have the scoring ability to consistently take over a game. Isaiah was a Hall of Famer and one of the best of all time consistently throughout his career. Rondo, while very good, isn't anywhere near that level.
If the goal truly is a Championship, then putting all your eggs in the "Let Rondo be the cornerstone of this team" basket is a horrible plan. Championships are won with all-stars at the 3,4, and/or 5 spots. Not with PG's with huge holes in their game.
Why not face the fact that we are not going to win with this team. While Ray, Pierce, and KG at one point were championship material, they all aren't now. KG isn't anywhere near the defensive presence he once was, and we don't have any consistency at the 5 spot to back him up with JO not healthy enough to be dependable. Rather than spend this year and next pretending we have a shot, let's ensure that we won't wallow in another 20 years of mediocrity by using Rondo to give us a chance at maintaining a winning team and with a little luck contend again. If not, 2 years from now we are likely to be the Washington Wizards...
