So, yeah, to be clear, there were three takedowns in the match. none of them was obviously a slam, but two could go either way.
There was another thread a while back where, horribly, a kid's neck was broken in a tournament. There were some emotional responses to the situation, mostly centered on the presumption that there was a slam.
Broken neck in BJJ Tournament (OUCH) Lots of information about what is a slam and what isn't in that thread.
It's kind of a gray area in BJJ in most cases. While some are super obvious, most are not. in general, in my experience, if you execute the takedown in a continuous motion, and are not elevating your opponent with the sole purpose of increasing the amplitude of the takedown, it's not a slam. So, that first takedown at :48 seconds was terrific and clearly not a slam.
However, at :56 seconds, there was a weird takedown where the BJJ guy seems to jump up to try and escape a guillotine or finger choke (can't really see it). I'd be inclined to say not a slam because the wrestler doesn't hold him in the air for long and the guy kind of did it to himself by jumping up to try and escape. But the wrestler does hold the guy up in the air for a clear moment before dropping him hard.
At 1:56, the single leg, that one could really go either way, again, mainly because the wrestler seems to elevate the bjj guy up, hold him there and then drop him hard.
As I said before, it's borderline. Looking at it again, I don't think it would be called often, but it's in that gray area.
