Part of it is the game has moved away from that. Post play is too ineffecient. Much better to get shots at the rim or open 3s instead of waiting 15 seconds as your plodding center probes for a semi-contested fade from 12 feet. I would 100% rather see a corner 3 attempt than a postup. The only value in the post now is passing, which you see from big playmakers like Joker and Bron. He shouldn't get low post touches and no one should. It isn't 1990 anymore. If you want an inside threat, get a good driver or cutter...which we have between Sexton and Okoro now.
As it were, even if this was the 90s, I don't want Drummond posting up because he is bad at it. He is strong and fast but tries to score in the post like he is Andre Miller not Dwight Howard. He has been pretty disappointing in utilizing the tools he has. It is much worse on defense, but that has been covered elsewhere. I don't mind trading for a year of Drummond since we gave up 0 assets. I expect he will not be on the roster by the end of the year. Hopefully we get a second or something for him, but I am not expecting a first at this point.
