Its not a criticism - simply put hit ups aren't in his job description. They generally save him til he can either run at backs in space or close to the line - when he's at his most dangerous. All the other forwards, and the back three will do the heavy-lifting to get him in that position, which is good for the team. And they're in the GF. There's no player that can run "downhill" (as I call it) as good as him.
Dont try and make it a reasonable thread. He doesnt take a lot of hitups in the middle because he plays on an edge, that shouldnt be hard to understand. Every good back rower tries to run at halves as much as possible. For you to say he never runs at forwards show you must really not pay attention. He runs at and over forwards often and he is taking runs in our own half often, if you think him running on an edge means its not a hitup well that just shows you're an idiot.
