I would be very surprised if Sturrock has not already apologised.
Smith will start the next game and then hopefully everyone will see this for exactly what it was , a decision based on a set of 'unique circumstances*(having a Keeper on the bench who 'won' the last penalty shootout)' that paid off.
If Smiths confidence hits rock bottom and he plays crap and Dan takes over and is no better then we can all look back with hindsight and say Sturrock got it wrong- and it cost us promotion.
If Smith comes back and plays just as well, or if he is poor but Bentley gets his chance and is great then it was a success.
Only time will tell
I would have liked to have seen Smith stay on, but TBH if I can could go back in time and keep Smith on and re run the penalties again there is no way I would do it
Which is what happened last season when Sturrock backed Daniels over Morris. Of course Daniels is a vastly superior keeper to Morris, but it killed Morris' confidence and an average at best League Two keeper ended up playing like a very poor keeper and it ultimately cost us promotion.
