Yup.
The highest last season (14/15) was 9.13 for Teixeira v Leeds (a). (There were 5 9+ performances last season, three of them were Teixeira, plus one for Dunk and one for Stockdale).
13/14 Only one over 9 rating, Ulloa at home v Burnley (9.08)
12/13 There were 8 of them, Kuszczak (two of them, highest 9.65 v Cardiff away) Bruno (9.51 v Wednesday at home), Ulloa (three of them, the highest being 9.40 v Palace at home)
11/12 Vicente got 9.42 v Derby, just beaten by 9.44 for Lualua in the same match, there were four other 9+ ratings that season but none above 9.36.
10/11 saw 7 9+ ratings, Murray got 9.44 v Orient at home, the rest were below 9.36.
So, the seventh highest average rating in the last 5 years. That's how far back my records go.
