Help us do what, exactly? Get past Toronto and Cleveland?
No rookie we pick is going to do that. So I take it you are in favor of trading for or signing a veteran, star player.
However, if we add a rookie who can fill an important hole (e.g. Hield with his shooting/scoring ability or Poeltl with his defence and rebounding) and then add another impact player via free agency or trades who can help us fill another big weakness or two (Dwight, Monroe, Horford, Butler, etc) then those two additions may well be enough to improve us to the point where we can really challenge Cleveland.
Remember that we gave an almost completely healthy #3 seed Atlanta Hawks team a pretty tough run without Bradley, without Olynyk, and with 30% of a Crowder. With those guys healthy, there's a good chance we beat Atlanta in that series.
I agree, with the statement in bold, but my assertion is that "with those guys healthy", we don't play a rookie like Hield very much if at all in that series.
Rookies like Hield get lots of minutes on bad teams. If we are another 48+ win team, we aren't going to give lots of minutes to any rookie unless they are a transcendent rookie. Marcus Smart was one of the very, very rare rookies to get lots of minutes on a team that made the playoffs in 2014, but even that was a sub-.500 team and he got minutes because we were almost a tanking level team in midwinter after unloading Rondo (which opened the door for Smart to enter the starting lineup) before we obtained Isaiah and fought our way through the back door into the playoffs.
Go look over the playoff rosters of NBA teams year after year. Rookies barely get minutes on playoff teams, especially _good_ playoff teams.
I am not opposed to forego drafting Bender (at #3) or Maker (later in the draft), per CoachBo's plea. But then I want to hear the realistic plan for transactions that will 'help us win now' to get over the hump in the playoffs.
And a realistic plan isn't going to depend on rookies.
That's not to say you can't draft rookies and have them on your team and still go deep in the playoffs and they might even be able to contribute here and there. But if you _depend_ on them as part of your plan to get there, forget it. That's not a realistic plan.
