Just think of it on these terms.
Last year we had Melo as a 20 points a night weapon, a very talented but up and down in regards to a 2nd option in Porzingis and no 3rd option - it was by committee some times Afflalo other times Lopez. We had no attacking guard who could run screen rolls or early offence. In contrast now we have a base to work with. Melo is still who he is, I think it's reasonable to expect KP to be a more consistent 2nd option maybe give us 17 ppg, and then we have Rose to attack the defence off the dribble create some early good looks and give us 3 guys who the defense has to worry about.
All we need now do be a really competitive and good team are two shot makers around KP-Melo-Rose. Players that can catch and shoot open 3 pointers or finish well inside as a big guy.
Even if we sign Allen Crabbe and Dwight Howard, we have enough talent there to compete with any team on a night to night basis.
Last years weaknesses were
- Point guard could not attack a defender or get into the paint.
- Not enough points or shots in the paint
- No 3rd option, inconsistent 2nd option
- No real transition or early offence
With a year older KP, Melo, Rose and 30$M spent on supporting talent I will be surprised if we can't get this team to make a decent playoff run next year.
