You could've said that about Ashbee, Dawson and the like at several points, but good players often step up and improve. I don't see any reason why they couldn't be good players for a top 6 side championship side, both of them are good all-rounders. All we can do is sign players for the positions that we currently need them in and worry about who is or isn't good enough for future levels we find ourselves at when that time comes. Right now we've got two good full backs on each side so we don't need to be worrying about that position at all.
Fair point re those 2.
I wouldn't be upset to see them both start, but I'd also be fine if we signed better if they where available.
