The new Giants offense that Ben McAdoo was installing was supposed to help “fix” Eli Manning after his disastrous performance last season. And maybe it eventually will. But right now, with just one significant preseason game left, the Giants’ quarterback doesn’t look very good and doesn’t look very comfortable.

And he’s also running out of time.

It may only be the preseason and still too early to panic — and Manning may not even be close to that point yet — but his performance so far this summer is certainly a cause for concern. He completed just one of his seven passes for a measly six yards in the Giants’ 27-26 win over the Colts on Saturday night. And that came seven days after his 0-for-2 showing against the Steelers.

Yes, it’s a small sample size — not even six full quarters of work in the Giants’ three games — but he has gone 1-for-9 for six yards over the last two games, at a time when he’s supposed to be rounding into form. Yes, it’s a new offense and he’s still learning the plays and the pace, but at the moment there is no flow or rhythm.

He never said it was going to be easy. But by now, shouldn’t he at least be a little better than that?

“No, I don’t worry too much,” Manning said. “Obviously you want to go out there and you want to play well. You feel like you should be able to find completions and do things well. But you can’t get worried at this point in time.”

Manning actually said that he has seen some progress in the offense. Players recognize the checks at the line better than they did in the past, and to him, the operation seems to be moving more efficiently. He also pointed out three major opportunities the offense had for big plays that just missed on Saturday night, including a 50-yard catch that ended with a Victor Cruz fumble and was negated by a penalty.
