He played a large part of that season. And nobody, not even you, knows what the scores would have been had he not got injured.
Yes of course. If he's played more than a few games this season then he's a part of it.
Has he dropped the ball only three times? 😉
But I agree. He was a gamble that didn't work out. Personally I think he's average for the Championship and there are plenty of examples of other keepers making mistakes. He's part of our history now.
