I mean, I am not in the heads of every one of his teammates but I would wager the ability to play through an injury does inspire confidence but probably not as much as the ability to put up the performance he did yesterday. If he would do that more, injured or healthy, I am pretty sure his teammates would definitely have a ton of faith in him.
Which, for all we know they always have. We aren't intimately familiar with the general thoughts of his teammates nor probably will we ever be.
This is just one of those speculative things that I don't tend to argue to vehemently about or even put much stock in simply because the unknowns are massive and the knowns are very small. There is anecdotal evidence in the way of public comments or teammate body language(which is very interpretive anyway) but aside from that the public is almost always very shielded from the true thoughts on specific players.
Winning and playing well seems to cure all the ails. Hopefully that just continues and this isn't really a debate at all.
