Fa'afili had his flaws but he seemed to attract more stick than he deserved. Everyone was quick to have a moan when he made an error but explained all his tries away as Gleeson putting them on a plate for him. He wasn't a winger that was going to excite the fans, given his style of play. Fans like wingers with pace who can go the length of the field and guys who can do that will get the benefit of the doubt from the crowd - everyone was rooting for Kevin Penny to make it when he went through a bad patch, and Allan Hunte who could be lazy was also a popular figure because he scored some burners for us. Fa'afili was the slowest winger I can remember at Warrington. He was basically a kick receiver and someone who could finish well from close range because he had a strong build.
Fa'afili's skill set was quite similar to Joel Monaghan, although JM was better. We used them in similar ways. JM benefited from playing in the TS era when we were winning Challenge Cups, whereas Fa'afili played in the Cullen era when we were signing lots of big names but always seemed to be the same underachieving side, hovering on the fringe of the playoffs. Fa'afili was probably judged in a more critical way because of the frustration of the fans during that era. I wonder whether if you swapped the eras where those two played, if JM would have attracted more criticism, as he was also a winger that didn't have great pace, and if Fa'afili would have been given an easier ride from the fans.
You could make a similar case for Mike Wainwright vs David Solomona. Solomona was a better player but they had a similar skill set (Wainwright had better stamina and work rate, Solomona better at creating magic plays, but they were both ballplaying forwards). Solomona may have been seen as a frustrating luxury in the Cullen era and Wainwright could have been seen as an underrated gem if he played in the TS side. I always thought Wainwright would have worked in the Saints side of the era if he'd been there instead of Bennett or Stankevitch.
Wainwright was a good player for us in his second spell. Cullen seemed to believe in him whereas DVDV never seemed to rate him. Moving away did him good because at the end of his first spell he had a really bad time where he was making handling errors, the fans were getting on his back and DVDV was making it clear he didn't think much of him. He came back a better, more confident player from his spell in Salford.
