Similar ideas have come up in other threads but I have been trying to get my head around exactly how things stand for both the regular season and the playoffs in terms of the roster/rotation. In my mind, there is one group of players that will be in the regular season rotation and a shorter list that will be in the playoff rotation. The following 8 in my mind are locks to be solid playoff rotation players:
Smart
Brown
Tatum
Horford
RWilliams
White
Brogdon
Grant
Beyond that, we have Hauser, Kornet, and Pritchard who are definitely regular season rotation players but probably not playoff rotation players. Then there is Griffin and Jackson who are not even regular season rotation players, at least not very often.
Whether you agree or disagree specifically with how I have grouped the players, the big question is if this is enough, particularly in regards to the playoff rotation? Of course it would be nice to have a playoff tested vet to fill in for any injury for the playoff rotation but I don't think that is realistic. We have to go with what we have on the team today and if any of the core playoff rotation players are injured, everything changes.
I feel that the core playoff rotation is sufficient, largely due to the multi-position versatility of many of the players. It allow us to be at least 2 deep at each of the traditional positions. These are the positions that these players can play in my opinion:
PG: Smart, White, Brogdon
SG: Brown, Brogdon, Smart, White
SF: Tatum, Brown
PF: Horford, Grant
C: R.Williams, Horford
Again, you can quibble with me whether you think Tatum can play PF or Grant C but I think if you look at it this way that it is clear that we have more redundancy with our guards than with forwards or centers. These are in my mind the positions that these players can play but you can deploy them in all sorts of combination, for example 1 big or 2 bigs. You can play Tatum in a 1 big line up but to me, that just means you are playing 1 big, not that Tatum is a PF.
The other observation I will offer is that we now have a series of games this season that were played largely with 1 big as the primary line up (while RWill was out and White often starting) and now that he is back, we have a series of games where we have been largely back to the 2 big line up. The Defrtg has improved some with RWill's return but not by as much as I would expect (abut 1 pt/100 poss in those 15 games, not all of which RWill played). Overall though, I have seen the defense improve, or so it seems. There have been several games with other players out so it is hard to do a pure sort on this. I believe we are a better defensive team when we play with 2 bigs as the principle line up (and also a better team overall) and I think that will be the case in the playoffs also.
So back to the main question. What to do to improve the team? Where should the focus be? If you think the best record is important, then a player who helps the regular season rotation, but potentially not the playoff rotation, could be something we need. If you are like me, and not as concerned about adding to the regular season rotation unless it also improves the playoff rotation, then we should only add a player (assuming you are giving up at least draft picks) who is good enough to be expected to help the play off rotation. Of course signing an available FA to a min contract changes the equation. I don't mind signing another Griffin type player if we don't have to give up anything. It is just that that type of move isn't helping the playoff rotation (and maybe not even helping the regular season rotation).
This got a bit long-winded (apologies), but bottom line, as we stand, our playoff rotation looks solid. A bit guard heavy at the expense of big depth but still solid, and hard to improve upon without a trade that involves giving up something of value.
