Dan Kennett has passed me a database that I’ll be using over the forseeable future. First up I wanted to see how reliable the numbers I use (from football-data.co.uk) are in comparison to those provided by Opta. Ted Knutson has taken a look at this previously and shown that shots on target don’t translate well between Opta and the available via football-data.co.uk. However, he also noted that TSR’s line up pretty well. Just how well? The sample below is for the 2008-09 – 2011-12 (inclusive) Premiership seasons, giving a sample size of 80.
I don’t have shot on target numbers to do the same comparison, but TSR’s line up pretty damn well. I think I’ll stick with the free stuff.
