What would prefer.
a. A positive influence around the club and a negative influence on defence
b. A positive influence on defence.
Whether Simmons is a positive influence at the club or not, really isn't what Tigers need. They need someone who can teach the team who to defend as one unit.
Furthermore, the only way to get rid of Sheens is a mass protest. Asking 20 forummers to not buy stuff isn't going to dent the Tigers coffers much.
You need a public figure, maybe even an ex player to have a go at Sheens. Tigers fans never get listened too, a lot of them are even attacked by Sheens.
