Think Boxall definately deserces a little higher, certainly higher than Sigmund.
Wasn't at fault for the goal, and kept a pretty good team fairly quiet (part of team effort). For me, he also looks more confident on the ball than Sigmund, has better distribution and seemed to be better at marking tightly.
Siggy makes a lot of great last ditch tackles which we all love, but they question never seems to get asked, why are they last ditch. Often its because he gets caught out and has to recover (which to be fair he does do well).
It seems some players we'll forgive anything and look to blame elsewhere (Siggy's fault for the goal completely is a good example) whilst others we'll pick to pieces.
Moving forward, Boxall and Durante in my eyes will offer more to the NIX, but despite this i can not see Siggy getting dropped.
