And assuming that is the case, it leaves wide open exactly how that "covering of defensive mistakes" is going to occur. Is it from a shot block (as Brick defines)? Is it from taking a charge? Is it through communication to teamates on defensive assignments in realtime action? Is it some or all of the above? The point of the matter is that it is presumptuous to assign to Malone a particular meaning of the term "anchor" unless he himself defines the term.
in the post you quoted, Chupacabra pretty succinctly stated that a defensive anchor covers for his teammate's defensive mistakes through his ability to negate scoring attempts at the rim. that is the generally-accepted understanding of a "defensive anchor," a big man whose presence in the paint results in shots being altered at the rim. roy hibbert, for example, is a defensive anchor in that, when he's on the floor during defensive possessions, his length, timing, skill, and role dictate that a shot at the rim will have less of a chance to go in than it would if he was not on the floor...
an offense must account for such a player, and such a player often forces an offense to take lower percentage shots as a result. a defensive anchor
shifts the percentages in your favor. that said, a guy like demarcus cousins will never "anchor" the kings' defense by taking charges, because you
can't anchor a defense around the charge. it's often a "could go either way" call, and that doesn't shift the percentages in your favor. you can't anchor a defense with communication, either. trust and communication are vital components of a successful
team defense, but if we're talking about
anchoring that team defense, there must be a last line of defense at the rim that can shift the percentages in your favor...
it just seems to me like you're going well outta your way to try and create a hopelessly semantic argument. it's not that "anchor" means one-and-only-one thing, but rather that demarcus cousins doesn't really satisfy the requirements of
any useful definition of "defensive anchor." he's the team's captain. he must lead by example. he must compete on the defensive end. but he's not going to anchor the kings' defense like a number of other roleplayers could alongside of him...
but if you really want to get pedantic about it, then malone's definition of "anchor" is likely too broad to be useful to our understanding of the team's defensive strategy. he might as well be saying that demarcus cousins is the kings' "batman" on defense. it could mean any number of things that don't help us contextualize each individual player's role on defense. but, if we tune our conversation to the generally-accepted understanding of what a "defensive anchor" most commonly represents in the contemporary nba, then we can determine whether or not demarcus cousins satisfies that understanding, and what personnel moves the kings need to make in order to compensate if demarcus doesn't satisfy that understanding...
in my mind, he doesn't, and he's not likely to become a "defensive anchor," or even get close to it. therefore the kings would be best served pursuing a defensive-minded PF that can alter shots at the rim...
