His OD is definitely a factor.
Does that factor even exists?
One of the original BBs said it existed and that is generally accepted.
Is it a pro or a con?
Its both. Its certainly a con when you lose a player because of two flagrant fouls in 8 minutes as I did once. But I think its worth putting up with the negatives. I'll finish by quoting your own post:
getting 6 fouls in 40ish minutes means he's actively defending
This is what I think is happening. Aggressive players defend better. In real life aggressiveness leads to taking more chances, like trying to block more, steal more. That just makes sense to me, I've always assumed it and its never done me any harm here.
Final answer: both a pro and a con, but more on the pro side for me.
