it is easy to believe that a young half who is a FG coach's son would be arrogant but I thought it telling that when it was reported that Flanagan was on the outer with the Roosters, Gallen implored the Sharks to re-sign him... so ego or not, I doubt it is to the level of being disruptive to a squad
I would simply think the Roosters acknowledged that there were some tough decisions to be made following Cronk's retirement with Flanagan recruited and Sam Walker and Lachlan Lam coming up thru the grades and Keary still in his prime (although a little groggy)
Flanagan needs to shut up now though... by questioning his axing by the Roosters, he is bringing on further unnecessary pressure onto himself to prove them wrong... it would be easier to say little and leave the narrative to the likes of Gus Gould, Andrew Johns and Fittler who defended him by noting how long it takes for halves to develop to proven FG performers
