He was also a perennial reserve grader and only got a look in in 2008, one of the worst NRL teams ever.
What you fail to appreciate about Morrin is exactly why I have a lot of respect for players like him. He worked incredibly hard for many years to remain in the squad. He didn't get a run until late in his career. But when he did he impressed many with his intensity.
He'd worked his ass off since he was a kid just to stay in the squad. I'd say he was displayed to the youngsters to show how hard they needed to work. If you put Morrins attitude and will to succeed into a lazy player like TPJ's frame he'd have been a fucking wrecking ball. Unfortunately he was not really the success that he deserved to be.
In the end a lot of players make it due to physical dominance. Some get there through hard work while others can work as hard as they like and never reap the ultimate reward. Morrin didn't set the world on fire in his handful of games. But he didn't disgrace himself either. I know that he deserves some respect for staying on the long road it took him to get to the NRL.
I have a cousin who was touted as a huge prospect at Wests. Unfortunately he's about five and a half feet tall and despite having packed on more muscle at times than seemed healthy, he's slowly slipped further away from his dream. Last time I spoke to him he'd had 9 shoulder surgeries as well as work on both knees aside from the 'assorted' category. But I see similarities between him and Morrin in that they were both giving everything they had to league despite the reality that it wasn't going to give as much back. IMO you have to respect that.
