In what year are we talking?
If KG and Pierce retired next year, I'd say that starting lineup gets us firmly into the lottery.
Two-three years away?
Why don't I understand that?
Rondo will be an all-star almost assuredly...
Bradley is one of the best wing defenders in the league...
Jared Sullinger in 3 years should be a double-double machine...
That's already three good players to build around.
An interesting comparison is to today's Grizzlies
Starting PG: Great passer, speedy, athletic (Rondo/Conley)
Starting SG: Primarily a defensive player (Bradley/T.Allen)
Starting SF: Streaky, athletic, average-shooting (Green/Gay)
Starting PF: Double-double energy guy (Sully/Z.Bo)
Starting C: Big, tough, defensive guy (Melo/M.Gasol)
However, that said...
Rondo > Conley
Bradley = T.Allen
Green < Gay
Sully < Z.Bo
Melo < M.Gasol
Up until this current year, Memphis was a borderline playoff team. And the reason they're doing so well this year is because their potential (Conley, Gay, Gasol) panned out.
I am confident Melo will not be as good as Gasol.
I am confident Green will not be good as Gay.
Sully could come close to Z.Bo, but I don't think he'll be as good as him.
Also, Conley's perimeter shooting makes up for T.Allen's weakness in that area. Rondo can't now and likely won't ever be able to be such a shooting threat as to make up for Bradley. So look forward to having zero floor spacing.
So, however you look at it, we would be worse than a borderline-playoff team, making us a non-playoff team. I'm pretty certain of that.
