There is that yes, I grew up watching boycs bore the life out of test cricket
He looks a little unsure on picking length or maybe unsure of the wicket?
Almost like he's a little too wary?nervous
And then he suddenly switches on?
Hope he bats all day
I think your nervous comment is correct. Not because he's worried about SA, but because he knows he's under pressure for his place and so goes into his shell. We all know if you go defensive you can make more mistakes, I think that's borne out then with the odd slog that appears. Good pull shot by him just then.
It's not boring though, it's an interesting passage of play. The more shots a batsmen plays the easier a bowlers job is to get them out (unless it's a flat deck like in Aus), so by only playing a 'shot' when it's a bad ball. .you are forcing the bowlers to bowl into your areas etc. They can't just plod away outside off, just as much as you can't jus tleave everything. YOu have to take 20 wickets to win a game. Unlike white ball cricket where bowling is even less challenging because you know the batsmen will be throwin gthe bat so you just bowl negative and wait for it. If you had to take wickets to win the game (ie, if you don't take 10 then you draw), you'd find bowlers would have to attack the stumps more, which in turn.. might produce more shots.
It's great fun when you leave well, defend.. and force a bowler into doing what you want. Just as enjoyable as watching someone like stokes, warner slog/biff on a flat track 4 after 4 after 4.
