I like the look of Phillips, has a more rounded game than the others with an accurate throw.
If Lake could sort his throwing then he'd be a shoe in, but wobbly throwers can go their entire career without being able to sort it out, so I won't hold my breath.
Dee is probably still second choice atm, but he really needs to kick on now.
Elias is the other option, but he's slipped back recently with some really poor displays for both the Scarlets and Wales. He could still come good, but needs to work on his consistency, especially at the set piece.
We really need a couple of those to step up to the plate now because Ken won't go on for much longer. He may make the WC, he might fade in the lead-up though.
