Not a lazy man's argument at all. Danny showed his true colors in 2011 when he made the most disastrous trade of his tenure - and lost banner #18 in one day - by giving away Perk for Jeff Green - if that ain't choosing soft, finesse (and inefficient athleticism) for effective size that fit that particular team perfectly, I don't know what you would call it.
I didn't say he never acquired post players, but most are projects or undersized or finesse guys. This always puzzled me a little given the Celtics teams Danny played on that won with the best frontcourt combos in history with Bird, Max, McHale, Parish and then Walton for a season (I know, I know, the game has changed). Maybe, but obviously size and interior scoring & defense still matter, a lot. Just look at the very top of the league.
