If he had the length of Kalanic (ooo err), he might have got it. I don't mean to have a pop at others, I just think we're too quick to put a blame on someone every time. If the only criticism is a sliced cross lobbing him then I'll take that.
Kalanic may be a better keeper ability and physically wise but like you say, the communication with the defence seems to be there which means he may not have to face situations another keeper who isn't in tune with his back line as much.
Steer will probably revert to sub eventually but he's earning the shirt now. At worst he's a very solid back up but he's young, improving and pushing for number 1.
A lankier goalkeeper may have got there but I don't see an error in where he was.
