I went for people I would like to spend some Vulcans time as opposed to who I think Will.
Johnson : Long kicking practice just for a couple of weeks , no more than a Month ideally, for mine that should see him stay out of the Vulcans for the rest of he's career as long as he keeps trying those kicks in FG. I would also have him come back wearing the 6 Jersey purely to do with the culture of the club because he is a stand off wearing a halfbacks jumper on a halfback fantasy as opposed to sensible numbering for the teams sake
Manu: As long as it takes to get him in condition for another position
Locke : Wing refresher course , play himself V laumape for that Left Wing.....
.or train him at center and again give him all the time he needs to crack it , possibly Laumape on the left wing in that case.
