Clearly.
You mention that games can't be sacrificed for player development during the regular season. I'm pointing out that even with Tom going hard during the regular season and not playing the younger player they were still inconsistent as hell, and losing to bum teams all year.
That's mostly down to the fact Rose was either out or finding his feet for 70-80% of the season - yet they still finished with the
third best record - only three wins behind Cleveland. And this is after Cleveland made mid-season trades (that completely changed the dynamic of their team) after they were struggling to stay afloat in the playoff picture.
Can you imagine how GREAT the Bulls would've looked if they even made half the changes?
Ask yourself this - what would Cleveland's record be if they didn't make those trades, Bron only played 51 games (after being out for the last two seasons) and for most of those games he was still struggling to find his feet? Would Cleveland have even close to the record they had this season?
Ask yourself what every playoff team's record would be is they had their #1 player only for 51 games, and during those games they had to wait for him to adapt and regain his form after being out for the last 2-3 seasons?
Ask yourself what the Bulls record would be if Rose played 70+ games and was healthy and looked like the Rose of old?
Because as far as I can see it, if Rose was 100% from the start of the season this team would have registered 60 wins.
In fact, ask yourself this - if Thibs managed to have the second best-win% in the league, all without Rose for over half the games he's been coaching in Chicago - what would his win% be if Rose NEVER had any serious injuries at all?
To spell it out for you, maybe his philosophy is at fault. Maybe instead of playing Pau for entire quarters no matter how he's playing, or playing Jimmy for 45 minutes vs the Magic etc he should have played the young guys. He played Kirk even though Kirk was killing them all year.
If his philosophy is at fault, then you might as well let the Bulls coach themselves. Because this 'standard' of coach you keep alluding to doesn't exist.
