Again, Islam got taken down by a fireplug-type fighter.
We disagree on how much that meant. I think Moses didn't lose the position because of "excitement," but because of how smoothly and casually Islam handled it, postured-down, and shook Moises off.
The real danger from Oliviera are going to be leg locks from the bottom, because I think Moises almost caught Islam, and Oliviera is significantly better at these than Moises.
It'll be an interesting fight for sure. I see Islam as similar to Oliviera. Both are tall for the weight, and calm, almost-emotionless fighters, both submission specialists as well.
I see Oliviera is more experienced and a bit trickier, whereas I see Islam as stronger and more physical. It's a very even matchup.
