As somebody said above, the reality is i doubt we will see Mears play much anyway.
I think Jones said last week that we are going ahead with the 3-5-2 but will switch if need be, as we are still only a few games into this 3-5-2 i imagine they will give it a go for quite a period of time to allow people to settle, get used to it, etc so i dont think we will be seeing much of any right back.
Mears will probably be on the bench, one of those who can cover anywhere, a chris baird type, maybe after having Crainie train and play preseason they decided he wasnt upto it and instead Big Dave has gone with somebody he knows and trusted.
His old club in the MLS also said they agreed a mutual termination and they believed he was signing for a championship club so not sure he was not good enough.
If we were signing him as a main first team player i would be concerned but its a short term deal, somebody Moore knows and trusts, its not exciting but its not the end of the world.
