Just to quote myself, I found what I was talking about. For anyone interested, go and google "Scott Pendlebury are helmets the answer" and it comes up with a link to the podcast, which 26 minutes in the following discussion takes place:
Jay Clark: He could command 1.5m on the open market...
Scott Pendlebury: But if he wants to win a flag, why would he go and then destroy a club's salary cap by asking for 1.5?
Jay Z: That's what I was going to say, is 1.5 too much?
Scott Pendlebury: Yes, if he wants to win a flag, that's too much.
Granted 1.5m is at the higher end of what has been reported, but interesting nonetheless.
