The main thing this team has going for it over the past couple years is depth. Pretty much everyone on the team can play. There's redundancies all over the roster. That's why you can experiment and start Jerebko and it might actually be successful. It says a lot about the roster parity. While Sully was great this season, an argument could have been made that Olynyk should have started over him. And while Crowder proved to be excellent this season, an argument could be made that Evan Turner deserved just as many minutes. There was so much decent NBA talent on this squad that the young guys basically got buried by default. I said right away that Rozier, hunter and mickey would spend almost all of their time in D-League. Even if they were good, it was unlikely they'd see minutes until the log jam was cleared or guys went down with injuries. Injuries are the main reason you're seeing the rookies finally get minutes.
On a lesser team with less depth they might have seen minutes sooner. There was a thread here recently about Devin Booker. Booker was taken just a few picks ahead of Rozier. The 19 year old averaged 20 points after the all-star break. It's possible he would have worked his way up the depth chart on Boston, but it's also possible he would have spent most of his time in D-League and never got a real opportunity. Booker played on a bottom 4 team and spent the first half of the season playing in 48 games and averaging 23 minutes. Rozier, on the other hand, appeared in only 18 games over the first half of the season and averaged less than 6 minutes per game during that time. Not really enough time to show anything. Would Rozier have found a statistical groove with bulk minutes on the Suns? Would we be seeing our first signs of Booker's talent in the playoffs had he ended up on Boston? There's maybe a little of that.
All we can really do is compare their summer league stats (since Booker never played in D-League this year)
Rozier - 12.2 points, 3 rebounds, 3.8 assists, 1.25 steals with 35%/40%/83%
Booker - 15.2 points, 4.8 rebounds, 1.7 assists, 0.7 steals, 40%/40%/88%
Sure, Booker was probably a little better - hence why he was taken 3 spots higher - but who knows what kind of production they'd have if roles were reversed.
