I might disagree with your idea that the Chicago Bulls roster is already can consider a championship team.
They have a good run last season, surprising everyone with their good chemistry right at the start of the season but began to show inconsistency during the last phase of the season. I am positive about this young team but believe me, even if they stay healthy last season, their chance to advance to Finals is really slim. They will soon get their own recognition but not at that time.
Not just to stay healthy but the Bulls need to build a second squad that can consistently assist their main core, especially in the event of continuous injuries. They are already composed of good role players and what they need to do is to add some more.
There are lots of precious role players that are just there waiting to be utilized properly by a team.
I agree. They look good during regular season, but they fall off during playoffs. Considering they have low winning percentage against top team, they still have lots of building to do to be considered a championship team. They are on the right track though. Maybe a year or two and a few key players will do the trick. Let's watch out how they will fare this season.
