yes.
being "good defensively" is more than defending. ill compare pionk and ADA.
pionk isnt there yet on the parts you mentioned and accurately i must say.
actually, deangelo excels in those areas pionk is weak. ADA can move the puck crisply, exit and enter the zone and skate it out of trouble. he doesnt give the puck up too quickly but pionk indeed does and sometimes without pressure. hes very mechanical in that way. ADA thinks more and reacts.
as far as actually playing defense, ADA is quite competent. his gaps are usually solid, his stop/start and hip swivel is good and his ability to read plays and turn the puck the other way is a strength.
pionk gives up too much space , backs up too much and doesnt engage enough. hes passive.
its an understanding of the position that pionk lacks. pionk doesnt process the game yet while ADA has that part down.
