Only me who wants to see JJ Kenny given the chance at RB? Sure we need a squad, but I would hate Kenny to miss out on game time.
With Coleman out for so long, even if we get another RB then I'm sure Kenny will still get games.
I am probably wrong, but I see Martina as a short term stop gap with Kenny as backup. Then when Coleman comes back we either get rid of Martina at the end of next season and Kenny stays as back up to Coleman, or if Kenny isn't ready (or good enough) we keep Martina as back up to Coleman.
There are so many games next season (hopefully!) that I still think Kenny will get his chance. It's too much of a risk going into a new season without a fit senior RB.
