It's probably the right call, but it does my head in that we're in the same boat again. I personally wanted Appleton to get more time, I was one of very few - I get why people didn't want him, but I didn't think we were actually that far off - but no one on earth said 'why don't we get Appleton an extra coach to help him out...?' - same with Larry and so on and so forth.
My feeling is that Critch benefits from the collegiate approach but given that Calderwood and McCall didn't stick around very long, I'm not sure how much he wants to do it that way... My take when he got the job with Garrity and Brunskill was that he must live and die by that choice. I can only assume he was given a choice within a budget of who would assist him and he chse what he chose.
