There was a time when a friend of mine used to play with 5 medium pacers against me bowling just those short red circled slow deliveries, it used to piss me off big time but I couldn't argue much as he'd say that it's part of the game. A few matches went on and I kept losing due to low scoring despite having wickets left at the end of an inning but with time I got used it, time came when I once bashed him for 6 6 4 6 4 4 in an over, I remember this figure because I still tease him about it lol. Now he never uses medium bowlers against me and importantly he rarely bowls those slow deliveries, that too only when he's sure that I might get deceived by not judging the ball and playing a shot which only leads to a catch but that rarely happens, mostly he gets hit for six.
So short of all that, my point is that these deliveries are totally playable, you just have to pay close attention to it and experiment. I play it as late as possible and only HOOK and PULL shot works best on em, I mostly play it on front foot, it's more effective than back foot as strange it may sound.
The real concern is spin bowlers, those dead two bounce deliveries where ball travels in slow motion, it's totally unplayable but most doesn't agree with me on that for some reason.
