seems to be the modern way to just think I've had enough I'm off
Swann was injured but said he would have played on if the series was in balance so take from that what you will
I'm not a fan of retiring mid series as seems a bit of I don't give a (No Swearing Please) or wanting attention but there maybe more to it that we know so hard to judge
I just prefer the classic of playing the full series you are picked for then announcing at the end
