There's a system in place to prescribe penalties for incidents.
Drainer broke Mitch Daniel's jaw a couple of years back, Daniel missed 6, Drainer missed 3.
Going on that precedent, two seems right, although both would be lenient in my opinion, although I did not see the Bruggemann incident, just going on what I've heard about Tyler's injuries.
Before he delivered the hit he kicked him while he was on the ground, 2 does seem lenient.
Witnessed a similar incident with this individual in a Grand final a few years ago thinkin he has issues
