I think some of you guys are misreading this IMO.
Firstly, I think if Martin stays it increases our chance of getting Adams because we become a real threat short to mid term . Martin seriously boosts our firepower.
i think RFC suits Martin at least for the next few years our team and the big stage seriously provides the stage for him to boost his earning capacity into the future via on field support enabling him to explode in the next few years which some of us are expecting.
TBH, If I was RFC I would up it to 600K and go from there. Why?, horses for courses, there are never absolutes in anything , everything is relative , the free will of the market is supreme, it is best for Martins welfare probably as well. You cannot let Martin go lightly.
As I said before RFC seriously could only entertain letting Martin go if we got Boyd and Adams(or an equivalent eg. pick 10 or player) in return. Martin is worth that much to our aspirations. BTW if pies are offering 400K to Adams , Martin is worth 600K end of story relatively.
A lot of this is arguing the point of the worth of players including Martin. I say sign him up unless GWS throw a impressive trade deal for us Judd style because Martin is worth that much to the clubs future despite what some may think!
