absolutely did not label them a failure. but are they convincingly better than teams who have come 6th at any point in the last decade? not particularly and in many cases i would argue other 6ths would beat the current brighton. Same for 7th, 8th and so on. This is a not criticism of these teams, they are doing well and getting deserved plaudits, but while they are achieving very well as clubs, there is no way they represent an overall improved standard of the league. The fact is the top teams are weaker than ever, the bottom ones are terrible, and the middle teams are doing well, as have done plenty of well run teams through the years. For example, i picked the last time we won it - which wasnt a very strong year either, and the 6th place team then was Moyes' Everton. They had come 7th, 7th, 6th, 8th and 5th. Harry Redknapps Porstmouth was a fantastic strong team and came 14th. There are countless examples of mid section teams that were very good like the current ones, but the top teams were stronger. Overall the league is weaker IMO.
Some more context, the random choice of 1997. 6th place a chelsea of di Matteo, Vialli, Lebeouf, Petrescu, Zola. There is often a complete revisionism that back in the 90s it was United or Arsenal and a couple of others but its absolutely not the case. Chelsea of 1997 would probably beat current Chelsea 9 times out of 10. Another random year of 2003. 6th place was Blackburn under Souness who also got a league cup semi final. Friedel, Tugay, Duff, Yorke and Cole (who got 26 goals between them), Lucas Neill, David Dunn. This was another really solid side that would comfortably compete in todays top half.
