Yes, understood. Trevor Steven would never have been picked in place of Hoddle, because he was a wide forward, but he was reliable and workmanlike. Presumably, Webb was also regarded as more reliable and harder working than Hoddle, although I can't for the life of me think of one thing Webb did that Hoddle did not do as well or much, much* better; play fewer risky passes, maybe? Track back a bit more? We can be confident he wasn't a better substitute goalie ...
Strangely, France never dropped Platini for a more industrious hod-carrier (no pun intended) type player, and I think that was the correct decision.
* Add as many "muches" as you deem appropriate.
Anyway,
