Marshall has hardly dropped a high ball that I can recall lately, although he's let one or two nasty ones bounce first. But even the best, like RTS, do that occasionally. The body language is full of enthusiasm, he looks like he is enjoying his rugby and relishes at chance to get the ball in hand and run at defenders. i've noticed at the DW too that if Hardaker forays upfield it seems to be Marshall, rather than the more experienced Burgess, who drops back to cover.
Burgess doesn't look in the same place at all. I don't see why he should be 'finished', but we need more from him.
