But previous history here wasn't a "non-factor." If Neal had no previous history at all, I doubt he gets 5 games. If you think about it, 5 games is actually quite a bit for an incident that didn't result in any injury. I have no idea on the stats, but I'd guess there would be very few suspensions of greater than 5 games that had no injuries involved.
Intentional knee to the head doesn't warrant five games? Repeat offender or not? It makes the league look like a joke.
If the league REALLY wants to get the number of concussions down, they need to stop looking at injury or non-injury on a play as a factor in suspensions and take things like a knee to a head seriously.
