I agree both were good players, but Keena Young and Trent Plaisted were far superior. Their offenses were balanced. You could feed them and they would battle for position and score it on the block.
Davies was similar. i enjoyed his game. Hartsock's highlights are going to show you jump shots. He couldn't post his defenders up and score 10 times a game. He had to settle for lower percentage jumpers and offensive rebounds to get the bulk of his scoring.
If I had to pick between both combos, I'd choose ky and tp. They were both real big men that held their own offensively and defensively. They let their wings do their thing and focused on their roles as BIG MEN.
