I've only just seen the game and I'm going to be, what seems to be, the odd person out here. I just don't think he played as poorly as some are suggesting. I absolutely agree that he's not playing at the level we thought/wanted him to be playing at but he didn't do a lot wrong yesterday. He was pretty safe under the high ball except for the one where Best out jumped him. But even then, he did well to still grab hold of him and stop him from scoring. And I think it's a bit unfair to hold the last try against him. We've seen Saab do the same thing to FBs when he has a mile of room to run. The bloke is an athlete and was at full pace with a mile of room, so expecting Weekes to tackle him seems harsh.
Yes, his impact in the back line was minimal and there was that one run where he just didn't get the timing right with Shu. But rather than send him back to the Blackhole, I'd be keeping him in FG so that he might get more time working with Shu and the rest of the backline.
We're going to be without key players for a while, so give the kid the chance to get things going with the blokes that are there now. Apart from dropping Johns for Arthur, I just don't see any value at this point, in continuing to chop and change the team.
