Dwight was always a force to reckon with on defense but his offensive game never came around like some had hoped. He could grab 14-15 boards a night and get 2-3 blocks without much effort but he couldn't provide more than 12-16 points or so unless a team played through him almost exclusively. He did his best when the Magic surrounded him with multiple distributors like Jameer Nelson and Hedo but they needed to concede to him a lot. If you look at his best scoring seasons it was on the Magic and they had multiple players averaging more than 5 assists a game.
When he went to the Lakers his lack of offensive game was exposed because they weren't going to tailor their offense around him. In response he complained about his touches, which made it seem like he capable of doing more than they allowed but based on how that year and every year since has played out, it was clear that it was Dwight that lacked the offensive game that warranted the touches he called for.
