Here are the biggest rivalries with bad blood between them heading into next season.
1. Bulls vs. Celtics
After the classic seven game series in the first round of the Eastern Conference playoffs the Bulls and Celtics are undoubtedly the two teams with the most bad blood between them. Rajon Rondo will be booed for the rest of his career in the United Center and likewise for Kirk Hinrich in the TD Banknorth Garden. By game 5 during their epic series a flagrant foul had become a normality, that's when you know that these two teams are hot for each other. There are emotional players on each side, KG for the Celtics and Joakim Noah for the Bulls. And don't think that Brad Miller has forgotten about Rondo's bitch slap in game 5. Don't be surprised to see Rajon hitting the floor hard at the hands of Brad Miller.
2. Celtics vs. Lakers
The Celtics and Lakers have been bitter rivals going all the way back to the Russell\Chamberlain era. The players have changed but the rivalry has remained the same. It is my personal opinion along with many others that if the Celtics didn't lose KG to injury they would have repeated as NBA champions. Going into the season the Celtics are going to be eager to show that they are still the powerhouse of the Eastern Conference. And God knows they have re-loaded themselves with talent, adding Rasheed Wallace and Marquis Daniels to go along with their already star studded lineup. Assuming that there are no injuries to major players on either teams it is my prediction that they will meet in the championship again and once again the Celtics will come out victorious. A major reason for this is because right now KG is like a land mine ready to explode, he had to watch his team get knocked out in the second round of the playoffs while he could do nothing. Expect Kevin to enter this season hungrier than ever and hitting his head even harder off the Basket support before games.
3. Nuggets vs. Hornets
After the New Orleans Hornets got trounced by 58 points on their home floor I expect them to come into this season eager to show that they are a contender. Once Denver makes their first trip to New Orleans I expect a very physical and emotional game on the Hornets part. If they don't have any different attitude towards Denver then they have no soul and don't deserve to even take the floor.
4. Detroit vs. Cleveland
This rivalry won't attract as much attention as the others but I still believe that there is a strong motivation in the Pistons' mind to disassemble the Cavs this season. Detroit has added the very dangerous and streaky scorer Ben Gordon and Charlie Villanueva. For the whole decade the Pistons have been at the top of the Eastern Conference and for 8 seasons in a row they were in the Conference Finals. Detroit is going to be looking to enter into the Eastern Conference hierarchy, which consists of the Celtics, Magic, and Cavs.
