No one knows what Leal's intent was. And no one especially knows where Leal was intending to kick him. He didn't look backwards the entire play, so to say he "meant" to kick him in the nuts is absurd.
Trying to be impartial on this...Furst committed a dangerous, non basketball play, when he pulled Leal's shoulder back and pulled him down with him as he was falling. Or...Furst was falling and just grabbed Leal out of instinct. That "could" have been deemed either a Flagrant 1 or Flagrant 2. Flagrant 2, in that situation, would have been excessive, but a hook and hold would have been a perfectly appropriate call on that specific part of the play. Then they landed on the ground, neither of them threw an elbow or anything, but as Leal was getting up, Furst hooked his right leg around Leals leg, purposely tripping him. Or...Furst was just trying to pull his legs close to get himself up? I HAVE seen that particular play called a Flagrant 2 before. And I'd contend that's WAY more dangerous than a kick in the balls would be. What if Leal steps wrong and turns his ankle, or buckles his knee? Anyway, tripping like that could have been a Flagrant 1, at least. Then, as Leal is taking off to run away, he kicks his left leg back. It looked like an intentional kick, and probably was. But, was it a reaction to Furst trying to trip him? Was he purposely trying to stomp on Fursts balls? Or was he just flipping his leg back to clear it from Furst tripping attempts?
Furst instigated the whole thing. His actions likely were NOT basketball plays. Leal's actions ended it, and it likely wasn't a natural action to get out of being tangled up. So...fair to take the stance that whatever Leal deserved to get, so should have Furst. Both Flagrant 2's...seems excessive, but o.k. Both Flagrant 1s...this is what I would have done. Shows there's a consequence to both their actions, but doesn't disproportionately punish. Or...neither gets anything. In no world would it have been fair to give Leal a harsher punishment than Furst.
