team building is so...damn...hard.
need a smart plan and alot of luck. i'm sure many many people thought the raptors should blow things up last summer or maybe the summer before but they stayed the course and struck when opportunity presented itself.
i think you go from bad to mediocre to good to great.
jumping from one level to the next is not easy - which is why you need good management that understands team building and chemistry. it's the difference between scouting ron baker instead of his back court mate in van vleet.
imho, there is no 1 single blueprint as the raptors didn't have any player drafted higher than 15 on the roster.
i think you put together a roster with as many good two-way players as you can. you need to play defense and you need everybody that can score. you can't have any real liabilities out there unless it's completely outweighed by some elite skill.
keep adding talent and then see where it goes. keep tweaking and see where it goes. sometimes you need to be a 2nd round and out team for a few years before getting to the next level. sometimes there's no next level.
there is no right way. there is no quick fixes. just good management and luck.
