It looks fine on paper, apart from we're a man light in the front row given Jammer did the work of 2 for the last five years plus Laffranchi isn't a front rower.
But what you have to factor in is our recent record with injuries. It's not coincidence. We've carrying players like Perry and Wheeler who quite frankly shouldn't really be counted as they will spend more time injured than available and when they are fit they're always 'coming back' from one injury or another so they're never really fit.
Try taking the usual (Over the past 3 years anyway) 8 or 9 out and it doesn't look so nice. Particularly the front row where injuries to say LMS and TP would ravage us.
