It would probably help, although I expect Sully (if healthy) to be a pretty good player going forward. They may end up including one of them in a trade for that better player. I think the players we have are somewhat better than people think they are, hence the hand-wringing that we aren't the 2-3 win team people were expecting us to be at this point in the season.
Well, this goes to the distinction I made earlier -- if the Celtics have a better record than expected this season because the young talent on the team is better than expected, then fine. That's nice. We don't need the high lottery pick.
If instead, it's because all you need to make the playoffs this year is a handful of borderline starter / rotation players and maybe one or two above averages guys, then that's not something to be happy about.
Anyways, I'm fine with a Celtics team with Rondo and Sullinger as the #2 and #3 guys, assuming Sullinger stays on track toward borderline All-Stardom and Rondo returns to what he was pre-injury. We just need to get a really good #1.
Among the current assets, that leaves the Celtics wit Bradley, Green, Bass, Lee, Olynyk, Faverani, and a bunch of 1st round picks of unknown quality to try and trade for that #1 player.
Either that, or you need to carve out max cap space (while still leaving room to re-sign Rondo and Sullinger) to sign that guy, and then hope he wants to come to Boston.
