Here’s the shots on target for Unsworth and Allardyce in the league.It's not weak, and it's not methodologically robust - but that's because it's based on the only data available, as I cant conjure up 5 more PL games that Unsworth managed to identically compare him with Allardyce.
I can only make a judgement on what's in front of me. If you disagree with the method, I understand. But what you cant disagree with is that we shifted 5 places up the table under Unsworth.
Unsworth: 2,5,5,2,5
Allardyce: 4,2,4,7,0,3,1,0,0.
Looks like he had a bit of momentum when he took over and then the attacking side has gone into sharp decline.
