Indeed, also he needs to go looking for work a bit more and on defence/positioning. On Sunday our winger Lee Robinson (bit of a lump too) had him on all fronts and put in a couple of crunching hits, big Les was very quiet come the end.
Which sums up my point, Vainikolo has the raw ability to do it though he's not the finished article - England starting XV is not the place to do it. There are better wings who should be starting.
