It's certainly possible. It's also possible that the manager bought him but couldn't help him improve his game or simply had no idea how to use him effectively. Which could be part of the reason they ended his contract early and sent him packing. Davidson, that is.
As we all know, any signing's a gamble, and we'll see how Kettlewell's recruitment has gone soon enough. Since it's his neck on the block, I doubt he finds this one as bizarre, ludicrous or dodgy as some on here.
