True but I don't think Jack would take a backwards step against anyone
That's one of the reasons why he's a great captain. Jack has unfairly copped some stick of late, mainly because he's got some injuries but more importantly, shouldn't be a full time mid.
Jack should spend a lot more time forward where he can use his strength to smash packs and make defenders nervous. Let him play CHF even for parts of games. His body is better suited to smashing through than deft side steps. He's generally a good mark and kick.
If we can get a gun mid and release Jack forward (and as a bit of a utility), then the Jack love will reign supreme again. And may he reign with an iron fist.
And boot!
