I'de be starting the summer with marsh, but I think there's a few things worth remembering within that.
1.We don't know how fit marsh is to bowl, he's had a freak run of injuries the past few years and could barely bowl after playing a few straight test's in the ashes/at the WC.
2.I don't think marsh is a massively improved red ball bat, relative to what he was before the ashes. If you bowl to him on a good length in general, he's not very good, particularly at middle stump
shows this. In that 100 he got coming back into the test side, england either banged it in short or pitched it really full to him, where he's always been strong. In that same 100 when england actually bowled a good length at the stumps, he got dropped in the 30's/40's once from that length than eventually got out to it in the same way. Given the state of Pak's bowling attack I don't think there magically gonna bowl well to marsh, and he's in the frame of mind where he's going to smash the bad balls away. Still worth noting
3.Green as an allrounder is way better than marsh in home conditions. Green averages 32.5 with the bat and 24 with the ball in home conditions and is a way better bowler than marsh. 135-140 KM/H an hour from 6'8 is a much higher bowling ceiling than marsh's current dibbly dobblers.
