It’s time for Brian Daboll to use those “Coach of the Year” chops he fully earned in his first season with the Giants, and that doesn’t necessarily mean posting a second straight win this week out west.

Daboll said the right things and/or made the necessary adjustments with the Giants down 20-0 at halftime Sunday in Arizona, and the Giants more resembled last season’s playoff squad in rallying after intermission for a rousing win — albeit against an inferior opponent — than they had in being outscored 60-to-zip over their first six quarters this season.

Facing the loaded 49ers on a short work week Thursday night, however, already was going to be a tall order for the Giants.

And that was before they announced four injured starters — most notably, Saquon Barkley and Andrew Thomas — will be out of the lineup against possibly the best team in the NFL.
