They should have sorted out a replacement back in 2017 when he was out with his broken leg. That happened in March, so they had a full summer to sign a RB then, and all of the January window too before he came back. That injury could have been the end of Coleman at the top level, so even when he got back in the team, signing a RB should have been high on the list. But this is Everton, signed a free transfer to plug a gap in the squad and just hoped he`d come back as good as he was before.
The only thing thats changed now is that we have a crocked RB in Coleman, a geriatric RB in Young and Patterson who seems to be not up to it.
