Sure, size matters, but so do cap space and future Nets picks. Or something.
OK, but this is a non-responsive answer to the problem raised.
"Sure, but we have great opportunities to improve the team this summer" doesn't speak to the issue of "Our core might be fatally flawed."
Yes, we can add to the talent on the team.
But what do we do about the makeup of the players we already have?
Signing a star this summer won't change the fact that the PG, SG, SF, and C in the starting lineup are all undersized.
I don't think this group can stay intact, no matter who they can or will add this summer.
