I suspect Kossy will lose the short bursts before his overall stamina - there's a reason marathon runners peak later than 100m sprinters, and as I've said there's a reason players drop deeper later in their careers.
On to Saturday... given they're likely to deploy a 352, does that put our 4231 at risk of leaving them a man over behind our wingers and going at our full backs? Their left wing back Lewis Page is quality, so maybe we stand them up man for man in the system we used v Stockport, deploy Donawa at right wing back and rely on our home advantage to pin them back rather than the other way round?
The suggestion of the two Justins down the same flank is an interesting one - I'd love to see it.
