These kinds of stats are interesting but pretty much meaningless without a context for them. Maybe he's instructed to shoot from distance more often by his coach. Maybe he ends up isolated with no other options more often than other strikers because of his team's tactics, so he shoots from tough angles. Maybe he actually isn't a particularly accurate striker but he gets himself in shooting positions more often than another, more accurate, striker might - so if you swapped them the actual number of goals would be the same.
From what I can tell too that stat is measuring accuracy as shots/shots on target, not shots/goals, but the "on target" measure is in itself misleading - a mis-hit shot which goes straight at the middle of the goal and is easily gathered by the keeper is counted as on target, but one which beats the keeper and cannons back off the post is off target, when the second one was a lot closer to being a goal than the first one.
Also, you probably wouldn't expect someone who's taken a lot of shots to be close to the top of the table for accuracy, because the players with the best shot accuracy will be guys who've only had one or two shots and they've all been on target, and then the guys who've had 2 from 3 on target will be next, and so on. I'd be interested to know where the other guys who are near the top of the total shots list compare to Wood in the accuracy ratings.
