I’d have loved to see Viv Richards play T20. Ditto Beefy Botham.Maxy. Gayle and KP back in the day. Warney bowling micced up. Lynn going apeshit. Probably still happens with other players now but Ive had my fix
But like you, I feel the novelty of T20 has worn off (for me). I crave high calibre, tense test cricket.
Just don’t think Sri Lanka will provide it. Hope I’m wrong.
