It's farcical to suggest a player has to decide between his club or his division.
There are a number of reasons why there are so few transfers now. If a player is lucky enough to be from a relatively strong division and has hopes of playing with Cork at some level it's then an opportunity to showcase his talent at that level, the reason some of the so called Superpowers are not enamoured with the idea of the divisions is because they perceive them as a possible threat to their success. Also the reason some of them have won so many counties is that they were benefitting from transfers from the so called smaller clubs, the divisions have helped stall that to a degree and levelled the playing field.
