I did think the same about why two legs, but I then thought the reason i reckon is because a few teams had wanted to extend play offs to incorporate more teams.efl dismissed that to keep everything as same as possible and therefore if they had then said only one leg they might have been a few upset about changing the format.added of course To the tv factor too.but most first legs in particular are cagey affairs get ready with teams out of fitness/sharpness for them to be even more cagey.i”d tip a few penalty shoot outs on cards.
