I'm not worried about our starting XV... when available. My concerns are when injuries take their inevitable toll; I'm unconvinced by some of the back-up players. Specifically at 9 and 12; but also a little deeper at 3 and 5.
At 9 Khan is still absolute class; but take him away and we're left with Cook who's only really shown and class in 1 of his 6 seasons; Allinson who's never looked of the right standard to be 4th choice at a premiership club; and Homer, who whilst showing promise needs to also show maturity, game management and consistency; and would be my choice to bench most games.
At 12, Tapuai is fine, and I've no concerns with Clark - but he'll often be busy filling in for JJ whilst the internationals are away; so we're one injury away from playing Banahan in the midfield again - which TBH doesn't worry me as much as it did this time last year.
Up front, Thomas is fine but injury prone (played too much too young); and Lahiff has made a good fist of transitioning... and is also still injured, leaving us starting the season with Knight and KPN... I just feel like we're well stocked for 3rd/4th choice injury cover players, but lacking a starting quality THP.
Right behind that THP though, we've got Attwood who looks like he's missed the boat for England; and how motivated will he be now? and Stooke - who's a fine back-up; but any 3rd choice #5 will be very compromised IMO.
I'd back or first choice XV against anyone; especially at home; but it's a squad game; and ~38 players will see serious game time this season; and we've got a few too many make-weights who aren't really the required standard for their place in the pecking order.
