He has 8 assists in the league, for context, as I don't think many would consider either Johnston or Taylor as overly attacking, Johnston has 4 and Taylor has 5.
Factoring in Tavernier hits corners and freekicks, again, admirable, his assist numbers aren't that out of the ordinary this season relative to fullbacks with of our main competitors and that is factoring them having superior attacking players would be your thought I assume given how poor you are saying our attackers are?
I would expect Tavernier is one of our top wage earners, we are about to enter what is a likely massive rebuild of the side, if a suitable bid was on the table, the notion he is untouchable just isn't out of the question to me. I wouldn't have much issue if we moved on from him, even accounting for work needing done in other areas of the team
