I thought Beard had come good before/on the Lions tour. Despite a lot of justifiable negatovity around his selection gievn who missed out, I thought Beard had an impressive tour.
However, his lack of physicality, especially in the carry, has been really evident again this season. There was a recent Ospreys game that demonstrated this best, he found himself out wide 5m out, was given the ball in space with a back defending him, you'd usually back a 19st (or whatever he is) lock to power over from there, but instead he got easily tackled and the ball turned over!
He looks a bit weedy to me on his upper half, especially compared to other second rows. I don't think every player needs to have bulging biceps, but as a professional athlete in a position where power matters I think there should be a minimim standard which he falls below imo.
