Yeah, they will fill out their roster with minimum salary players for the next couple of years. But, rumour has it that Chris Paul will join them when he becomes a free agent.
They will win a championship one day...the Celtics won with Allen, Garnett, and Pierce and they had a good bench, but I don't think you need a good bench when you have 3 elite players like James, Bosh, and Wade. Also, it's not like they are all the exact same type of player, they are all different and will play well together as a team.
I think they will definately win a championship, but if they never do, will I care and feel bad for them? No....
