You can't realistically depend on 5 batsmen to make 400+ consistently though. You'd need the top 5 to be averaging between 70 and 80 a piece, which is never going to happen. We've only got 1 batsman averaging 50, so expecting them all to average 50+ is not realistic and not good for team balance. James Foster is the best option with the gloves, but he's unlikely to average more than 30 with the bat, so we'd need to drop a bowler to incorporate another batsman for this Test, meaning we'd more than likely not have enough bowling, and then Fred would come in when fit, which just doesn't provide enough batting. Davies would probably be a better all-round option than Foster.
