I totally disagree. For starters, basketballreference.com has him playing SG for more than 90% of the time during his two years in the league, so you are basically guessing when you say he's a SF. Besides, for his career, at 10.6, Simmons PER is not only well bellow the league's average - which is 15.0 - but also decreased 11.9 to 9.9. So, basically, Simmons sucks statistically. He looks, to a certain extent, like someone who can create his own shot but nevertheless was assisted in more than half of those. Burks, in comparison, has been assisted in less than 40% of his shots. By the way, he and Burks are quite similar in many respects: they not only have same height, good to great athleticism, but also are inconsistent in their shooting both from mid-range and from outside. Simmons finishes better near the rim, but Burks has been truly awful at that the last few years. On the other hand, Burks is two years younger than Simmons. All in all, signing Simmons would be a very redundant move, IMO.
Ehh, I would call him more of a 3. He played next to Ginobili more than he did next to Kawhi (about equal tho). He is definitely someone who can be either, the problem is that he just cant shoot.
