He was dropped because a bad manager made a bad decision.
If you follow stats you'd know that Scott Loach conceded 1.15 goals a game last season compared to Ben's 0.78. You'd also know that Ben kept 22 clean sheets to Loach's 16. Despite playing 7 games less, Ben still had more clean sheets than any other keeper in the division, for the second consecutive season.
You can carry on talking nonsense about 'following the stats' but the most basic stats you could possibly come up with for keepers proves you wrong.
The lengths you'll go to to justify your dislike of Hinchliffe is really weird.
