My initial thoughts are the three teams coming up could struggle quite a bit and could all end up in the bottom 4 or 5 places - however, in recent seasons the teams that have come up have done, on the whole, not too badly with the exception of Reading and QPR so I guess there must be a realistic chance that one or more of the three promoted this season could survive and one of them do exceed expectations.
Whether that is Cardiff or nor I would not like to say before the season gets underway again
