Marsh

All over 30 and in line to play champions trophy. Some of them are 3rd or 4th choice back ups for spots in the test team so I'm happy we have moved on. The ejection of Marsh is the most obvious choice. He is behind Webster and Green and at his age should just focus on white ball cricket and making money in t20 competitions.
Add Zampa to that list, as he's usually in the conversation.
TBH, I wouldn't be sad to see none of the 5 (the 4 you mentioned plus Zamps) selected for Tests moving forward.
Crickets a funny game, 12 months ago Marsh would have been undroppable. Now, we can't see a way back in for him.
On a slightly unrelated note - Smith was talking about going to the Olympics in 3 years, and focusing more on the shorter form. Makes me think he may retire from tests following the next Ashes. It's conceivable that Khawaja, Starc and Lyon may also retire around then
