That's fine for you to have that opinion. It certainly works for some goalies. Down early generally means exposed top corners and down late means five-hole exposure. There is no right answer and it's an individual thing that you work on with your goalie coach. Like any other tactical decision a goalie makes there are pros and cons that are individual. The point is to fit tactics to 1) player strength and 2) situation.
My point with Talbot are:
1) He's a great skater and a big man... which is a nice combination. The top corner exposure he would experience if he uses those two strengths will be far less than an equal-skating 5'9 guy. Thus the decision to be down more than most might well be deliberate AND correct given his strengths
2) You need to watch that goal again... I did, about 10 times yesterday when someone rightly pointed out the rebound was of Talbot's doing. (there are reasons why he did that that are beside the point... posted elsewhere)... but once you do watch it, I don't know how you can say that he saw that puck. There were literally 3 oilers in parts of that lane, plus a Penguin who vacated immediately as the shot was taken. No way he had a good look which is evidence of his reaction. A goalie lifting his glove in exasperation (which Talbot RARELY does) is a definite tell. Given limited sight, 10 out of 10 goalie coaches will tell you to get in the butterfly and stay big. So TACTICALLY he did exactly the right thing on that aspect of the play.
