Strength is one of the biggest things Wood needs to work on, as he is nowhere near as good of a defender (or post-up threat) as he could become once his body fills out. But it's far from the only one.
Wood has poor fundamentals on defense, as he tends to bite on pump-fakes regularly, and shows limited awareness off the ball in terms of positioning. He struggles with the nuances of the pick and roll, not always executing his team's game-plan, instead looking hunched over in a stance, and getting blown by off the dribble.
Inside the post, Wood is not particularly physical, as he tends to just stand straight-up and allow stronger players to catch the ball with deep position without putting up much of a fight. Once they catch it, he doesn't do a great job of bodying up his matchup or trying to hold his ground to avoid getting backed down. He doesn't appear to be the toughest or most contact loving player around, and his intensity leaves a lot to be desired as well in terms of his ability to give a second effort.
It's not rare for example to see him jogging back on defense and getting beat up the floor by the opposing big man.
His feel for the game leaves a lot to be desired as well, as he doesn't seem to have any real concept of what his limitations are offensively at the moment, which is a real issue considering his lack of polish. Reading the floor or making simple plays is not something that comes natural to him. Wood's 8.5% assist percentage is one of the lowest rates among players currently projected to get drafted—he not only does not have great court vision, but also has a tendency to play somewhat selfishly at times.
His shot-selection and overall decision making are fairly crude, as he tends to settle for wild shots early in the shot-clock without any regard for time, score or situation, and also forces the issue badly with his drives, leading to turnovers. He has a difficult time dealing with double teams, and is fairly predictable inside the post, making him relatively easy for opposing teams to scout and game-plan against. It's not rare to see his teammates or coaching staff becoming very frustrated with his antics on the court, and his body language can leave a lot to be desired.
