Most of these are BS and some are total BS.
I am concerned by Al's performance 3-5 years out when we'd re-sign him heading into what is usually a period of decline. This is a good year for bigs and we have Rozier and picks we could use to move up and not touch the starting core. Bigs take longer to develop and in 4-5 years Al will almost certainly be fading while the rest of team is in its prime.
Other than that, we're the envy of the league. The other contenders, GS, CLE, and HOU, are 3 of the 4 oldest teams in the league. We're the fifth youngest and if we were reasonably healthy we'd be in the Finals right now and not Cleveland. The only other teams who are young and good are POR which has cap issues and got swept by NO, TOR whose two best players are 29 and 32 going into 2018-19, and PHI, who has a slew of issues to overcome to compete with us.
We're in great shape and, barring injuries, we're going to win #18 soon.
