When the whistle blew on Sunderland's up-set victory over Manchester City, the 2011-12 Barclays Premier League reached its half-way mark, with 18 of the league's 20 teams having played their 19th match (Tottenham and Everton have one to make up). It's a great time to take inventory of each club's season and break out the report card: How does each club grade out through half of the season?
Swansea have been the surprise team for me this year.
