Not sure about GMS as he can be a bit of a lightweight. That said I think our regime would toughen him up somewhat, it's happened with others we have signed, where they have bulked up somewhat in their time with us. His lack of game time at the tattie howkers is quite possibly nothing to do with his ability. They have a number of players who can play his position. He wasn't signed by the current manager which may mean he is out of favour simply because he was inherited. Sure he would be a gamble, but lets face it so are a lot of players we sign, at least from the fans point of view.
I watched Maynard's 2015-16 goals and he scored with some good finishes. Looking back at his earlier ones from 13-16 there are a lot of good goals. I think he will do a job for us, if he is given a serious chance, and not just comes on for the last 10 mins.
I think Maloney would be an interesting signing. If he retains much of what he once had, he could still do a job for us. If he remains relatively injury free, I think he would be desperate to do well, so would put in a good shift. Remember with Robson people questioned the signing, but he was excellent for us, especially that first season.
I'm sure there will be plenty of people will disagree with some or all of the above, but that's my tuppence worth.
