If you ain't got 90+ chechking, you ain't even close to being a power forward. Heck, even 99 should be the limit given how easy it is to earn TPE these days. I had 90 in my first season, and 99 by my second. During my time the only other player to do this was Lobo I believe (Marcellin got there too I think, but nearer the end of my career - can't remember in fairness). It always irked me how Jenkins/Reikkinen got so many hits with only maximum 80 in checking.
It's a shame how few there are in the league, I think every team would be served well by having at least one. Plus, it's fun to see your dude rack up 10+ hits a game at times. I think for newer players though, and in general, points are sexier than hits.
With the update scale the way it is, you'll never have real power forwards anymore because it is just too easy to get 99 in 5 different categories (would love to change it but whateves).
