The pack has been letting the Scarlets down over recent seasons. They've lacked grunt in their front five. I feel the signings they have made will go some way to addressing that. The locks they have signed are big lads, who will add grunt in the scrum, ball carrying options in the loose and genuine lineout presence. They've also signed an apparently very competent scrummaging tightead who will hopefully sure up the scrum against the stronger scrummaging sides they'll face in the HC. Add that to the two extremely promising new props coming though, and the fact that all their efforts developing the young players in their region is really baring fruit (North, Scott & Liam Williams, McCusker, Shingler, Murphy, Rhodri Jones, Ken Owens, Fenby, Priestland, Knoyle, Gareth Davies, Rhodri Williams, etc.), and I think we should be expecting the Scarlets to compete with the best in Europe.
