We (me included) are a little short-sighted when it comes to player development. I don't think we appreciate how many drills, and how many individual steps have to be taken to develop one area of someone's game.
For example, I read Lowe's 10 things today. In it, he commented on Adams' new ability to dribble twice going to the basket. Here is what he said:
"Player development coaches spend entire seasons teaching big men their first one-dribble move. Once they have that down, it might take another year of rote practice -- and maybe longer -- for the big galoot to master two- or three-dribble moves with enough confidence to bust them out in a game. Anthony Davis went through that exact progression, and only now, in Year 5, is Davis comfortable bringing the ball up the floor and taking a bunch of decisive dribbles on the block."
As recently as last year, we needed another shooter because our shooting was bad. We were 24th (and lower than that for much of the year) in 3 point shooting. This year, we are 17th, and I notice that our shooting is not talked about as much. Crowder, Bradley, and Thomas have all upped their percentages. Both Horford and Olynyk are below their career averages and in a slump (maybe baby Horford is keeping Al awake at night?), but overall we are clearly a better shooting team than last year.
What happened? I don't know, honestly. The oversimplified answer is probably "Our guys put in the work," but is that all? What footwork, coming off screens, tired shooting, etc. did they learn that has aided their development? Part of it is comfort with one another. Part of it is reps. Part something else.
That brings us to our current weakness--rebounding. But what exactly is that a weakness of? Is it all jumping and fighting for boards, being really tall, and being really strong, or is it also something else? I honestly am not a good enough basketball mind to know, but I think part of the rebounding woes has to do with defensive rotations and loss of integrity on our team defense. If we get out of position, then we won't rebound well.
I think that Ainge and CBS are, instead of trying to solve the problems through drafting an average rebounding big or trading for some over-the-hill average big, developing their talent from within. The road to mediocrity is lined with short-sighted moves to shore up weaknesses (See Wizards, Washington).
I think Horford can rebound better once he gets into our scheme a bit more. I think Olynyk can rebound better, or at least tap rebounds to teammates better. Rozier, Brown, and Smart can all be doing what Bradley is doing to help our big men. If Crowder ever learns how to fight/box out without getting called for a foul, he could help more. The top rebounding teams all have their forwards and guards helping out significantly. Maybe that's what CBS is developing, but it's just not there yet.
I guess my point (and I am preaching to myself here too) is that player development doesn't just happen in the box score. It happens when a guy does a drop step, or makes the right pass even if it doesn't lead to an assist, or boxes a guy out so a guard can clear the rebound, or comes around a pick and gets his defender on his hip, or etc. Maybe there are ways our guys are developing in rebounding we don't see. Maybe by the end of the season we won't even notice the rebounding issue.
