crazy idea but if fit would you consider playing lachie henderson up forward and give sav a spell?
What you suggest might work if Hendo or Harry play forward to occupy McGovern. But then who rucks when Stanley needs a rest?
If Sav is given a break and from what I have seen of Fort / Abbott/ Krueger, I would play Abbott deep forward with Hawkins further up the ground. (in fact if Sav stays in I would do that anyway and Rohan a bit further up too).
What worries me most is Sav continuing to struggle and losing all confidence. Parsons was picked for far too long a time after it was obvious his head was going down and he is only just starting to recover (if he ever does).
