Signing Lee Griffiths was always questionable at best, but as has been pointed out finding the lynch pin in midfield is probably harder than it seems. I'm not sure even signing midfield upgrades on loan (e.g. Finlay Pollock) would actually help just now since without that enforcer they may be swamped.
Watson and Griffiths go right back to the Hutchie days so Watson will know Griffiths well and maybe know how to get him onside. From what I've heard Griffiths has always been a bit mental right back to youth days.
