Went out the window when they selected this squad?
I share your concern but out of the guys realistically in contention... Haskell? Wood and Clark certainly aren't major ball carriers. Itoje maybe? Burgess probably isn't ready, Ewers isn't there...
I'd like to take this opportunity to start the Mako for One platform, because we won't be selecting ball carriers anywhere else!
You may think that, but Stuart "What's that Tom? You've finally done 80 minutes after a year out with a broken neck? Want to play some international rugby?" Lancaster clearly thinks differently.
I have to admit his injuries makes me a little wary of his inclusion but if he's fit enough to get some warm-up game time, I'd be interested providing the doctors were saying "Probably won't break until three games after he gets back to Leicester as normal".
edit: Launchbury has fantastic work rate, pace and vision for a lock, but he is still a guy playing lock, where as Croft is winger quick with less pushing to do.
