The Rangers need smart defensemen. They are a low IQ group. Pathetic decision makers. I don't know if it's AV ordering them to float, vacate the slot and chase, chase, chase, but for veterans, these guys are stupid and make rookie mistakes every game. The unforced icings, bad line changes, empty low slot, McDonagh's stupid puck fumbling while walking the line with two men on him. Watch the Kings or Wild defend.
They need 4 dmen who do nothing but defend. Smart, poised, tight gaps, crisp passes, smart reads. The other two can be thoroughbreds. Right now they have 4 low IQ defenders from their own blue line inward -- Staal, Holden, Girardi and Klein. McDonagh's IQ is slightly above average. Skjei gets a mulligan because he's a rookie. Smith is average and probably a goner on July 1st.
Day and Zborovskiy are dumb decision makers. At least in the defensive zone. Tons of God-given skill and upside, but their approach to defending -- reads, slot coverage, body positioning, releasing, anticipation -- are poor. Skjei was excellent at all those things at Minnesota. Give him time and he will play the same way in the NHL.
I'm rooting for Day, but he still makes the same mistakes. Give him two years in the AHL. If he doesn't improve by then, move on.
