My gut feeling is that because we haven’t given consistent game time to the second stringers, every time we bring someone in we are going to look a little off (Coady, Yunus, Casadei in particular)
Striker is a key example, Daka getting consistent time = him scoring and playing well. JJ playing more as well has certainly helped him vs start of the season.
I would also say that they should be getting game time because they deserve it not for rotations sake.
I think the second string is more than good enough, just hasn’t had time to figure out the system when they’ve haven’t had lots of time in it vs the regulars.
