OK...no one anywhere on the planet, including Warner and Collins, had any expectation that Eli was going to start game 1 of his first season. It is precisely why they were looking for a vet. But everyone on the planet knew that the Gmen would be looking for any reason to put Eli in.
Whoever took that job damn well knew that he was going to have to play lights out to keep that job*.
Not "good enough", not "OK", not "passable" - lights out.
Takes a strong man to stand there and say "I can do this"
Warner did that.
Collins would not.
Not so much a knock on Collins as a pat on the back to Warner.
*And I know that you are fond of pointing out Warner's record with the Giants, but I don't think even Harooni would use the term "lights out". I would have kept him in, as would you, but it kinda proves my point, doesn't it?
And I probably should have put "babysitting" in quotes as you did, since it is the exact word Collins used.
