So true, its the same as releasing reliable midcarders that can flip between midcard and main event (wyatt, keith lee, strowman etc) and employing the likes of omos, commander ajeez, tamina, dana etc who cant step up believeabley,
When you put all your eggs in same basket, and only booking certain people strongly, if they are missing then you are screwed.
They only booked becky, ronda and charlotte strongly on the womens side leading up to wrestlemania and after for a while and then ronda left, becky got pregnant and charlotte took time off so it was left to sasha, asuka and bayley to save the womens division but then when becky and charlotte came back they went straight back to being the only strongly booked women so wwe didnt learn anything from that (i like becky and charlotte obviously but their booking is not helping anybody really, not even them cos who is believable to beat them)
Smackdown will have the same issue if roman has to take time off, he has killed everybody on the mens division off smackdown, who can step up if he not there (drew and sheamus i guess)
