Two goals from former Wanderers forward Jonathan Walters steered Stoke to a 5-0 victory in Sunday`s semi-final at Wembley.
Matthew Etherington, Robert Huth and Kenwyne Jones were also on target as Tony Pulis' side ran amok.
Coyle said: "I will analyse it, as hurtful and horrible as it will be to watch it again. We have to learn from it.
"Was the stage too much for one or two of them? Football is not just about physical ability. There is a mental strength that goes with it. I loved these occasions as a player.
"There were too many who didn't perform anywhere near to the right standard. We had a number of players who were at the bottom of the ladder. It was never going to be good enough against a very good side."
