I think part of the problem with Manu and also Yeaman to a large extent, is that they're runners.
Runners need gaps or at least a bit of space to create one. We treat our running players like props = Pass and drive.

There's a total lack of creative/inventive play/players.

Until last night Manu has been our best player.

As for Tickle. He has been very poor this season.

If you want to see a player lazy in defence then watch Tickle. Watch the try by Judas in the Derby and although Horney took his dummy he was Tickle's man to tackle but he was taking it easy Does that far too often.

Manu is a 40 minute impact 2nd row and not an 80 minute starter. Agar uses his wrong. FWIW Manu isnt the only player that Agar appears to be mis-using thus making them look dis-interested.

For me Manu has lost too much weight and is not as effective when going in to the collision. When he was bigger and playing in short stints ala Feks at Wigan he was awesome to watch. Manu i clearly an impact player and a naturally big bloke. He ought to get that bulk back on and he should be used in 15 minute stints. As for Yeaman he too loks leaner and less powerful going forward, looked shadow of his former self last night, God I remember him ripping JD to pieces one year not so many moons ago on his way to scoring 4 tries!
