For the most part Hood has been great on defense. I thought he did the best on Murray last series and held his own on PG in the 1st series. We're talking about guys like Harkless, Aminu, and Hood who have a ton of experience in this league and comparing them to a guy who just saw his first real meaningful "consistent" minutes this year. I completely disagree about development not needing actual game time. Having in game film where coaches can show him what he needs to do differently is invaluable. Sure, some players never really work hard enough to get past those bad habits but I do think that is correctable.
Jake played a lot PF in college. I am 6'6" but am almost always guarding the opposing team's tallest player in leagues I play in. Put me in the NBA and I don't have the lateral quickness to defend guards or wings so I'd never be able to be a shut down perimeter defender no matter how hard I worked at it. Jake I think does posses the skills to become a good defender eventually. I never said he was now but if he lowered his stance like
@TorturedBlazerFan said, learns to navigate picks better, and learns to be in a better position to closeout on shooters I think he can become more than adequate at perimeter defense.
