So far, to this point in the preseason, Giants QB Eli Manning hasn't shown us much. The Giants have trotted him out to make some calls at the line of scrimmage and mostly hand or throw it to his running backs.
With left tackle Will Beatty back protecting Manning's blindside on Saturday night, there are no more excuses. The Giants have their projected starting offensive line protecting their starting quarterback. They can now open it up (a little bit) and show some of their new passing attack.
They don't need to display everything. Some of the innovative stuff can be saved for the regular season, but some of the basics (deep sideline and vertical routes) can be practiced in a live game setting against the Colts.
Of course, we'll be watching and breaking it all down, because that's what you do with a quarterback working in a new system. You look for hints of what is to come in the regular season.
Two specific areas pointed out in this article to watch for are Manning's downfield throws and communication with WR Rueben Randle. So far in two games Manning hasn't thrown more than 10 yards. Last year communication with Randle wasn't great and as recently as Thursday in practice it lead to another INT so it's still a work in progress.
