I'm now continually fighting my first instincts with Lewis (dump him), he's only young. Many young HBs have all the attacking flair but are turnstyles in defence; Lewis however is a great defender with attacking eye but needs work on controlling a team and controlling a game. He's 23 with 24 games under his belt, still too green to completely write off. Plus he still needs another off-season or two to get to his proper playing weight.
He could be a great ball-playing lock, but with our lack of halves and overabundance of 2nd rowers, that won't happen here for a while yet (if at all).
Regarding the Broncos, I think the last thing they need is another green half. Their senior players need to step up or piss off.
