I knew what the point you were making was but you massively exaggerated it with the stat you used.My point is you have had in the past players score a lot of goals for a really poor team.
As for your underlying point, I agree to an extent but 30 goals is not par for the course. Only a handful of players have ever scored that many goals in a 38 game season and I'd imagine Phillips (Sunderland finished 1 place higher than Spurs have this season btw) is probably the only other that's done it in a side that's not finished in the top 4.
