That's definitely true. I think, though, it's relatively easy to tell whether it's going to be that kind of night for King pretty early on. Last night, it was pretty clear that it wasn't going to be his night offensively, so I really wasn't too upset about his foul trouble.I think the main difference between King and Watson is offensive potential. King isn't going to give you 15 points every night, but he can on any given night, and Watson definitely isn't as he just isn't that aggressive at this point.
That being said, I also thought last night was one of Watson's poorer games. Didn't make a huge impact defensively, was slow on some rotations, and had that one awful turnover. Not turning it over is key for Watson, because when he isn't making huge plus plays (other than some offensive rebounds), he has to avoid those negative ones, which he typically does do better than King (Watson's 13.5% turnover rate vs. King's 19.7%, the second worst rate on the team).
