I found this outsider's take from Fantasy Alarm rather interesting even if I don't agree:
Despite finishing 11-5 last season, the Giants have some serious issues throughout their roster. They basically got by with unconscious play from their high-priced defense and one-to-two game breaking plays per game from Odell Beckham Jr. While impressive is an understatement for their 2016 accomplishments considering what they were working with, you can’t with a straight face argue that this is a repeatable recipe for success going forward. Serious changes are needed throughout this Giants roster…
First here are some of the reasons I think that this author could be right:
1) The Giants had a relatively easy schedule in terms of how the schedule fell when the Bye was and the strength of the teams played. Not sure this can be repeated
2) The Giants were relatively healthy although they did have key injuries to Will Johnson (that cost them their FB), Darian Thompson (who seemed to prevent the other team's big plays), JPP (especially in the critical GB game) and assorted issues with offensive linemen. Still they had been healthier than in previous seasons
3) The Giants won almost all the close games. Not sure that's an easy feat to repeat.
Now there are reasons to think the team will do as well if not better than last season
1) Ben McAdoo is no longer a rookie head coach. No doubt Ben has learned important lessons after his first year ever being a head coach
2) The coaching staff is maintaining its continuity. This is very important in terms of players knowing their assignments to drafting and acquiring talent. Continuity is a key building block of success
3) The team is almost completely intact. Even if Hankins walks (there are still other FAs or draft options), this team will have another year playing together and knowing the system.
4) The Giants had a championship caliber defense last year. While there is not press A to continue, there is no reason to think the defense will not continue to excel. Considering how many new defensive starters there were last season, you would think the continuity of players in the system will only make things better.
5) The Giants have already fixed to critical offensive holes in signing a big WRs (something lacking last year) in Marshall and filling the hole at FB and blocking TE in Ellison
6) The team does not have father time hitting them at many positions. With the possible exception of Eli and maybe DRC there is no reason to believe the team will be seeing much in the way of age-related decline
7) There are a couple of 2nd-year players who should be reasonably expected to improve. The physically talented Eli Apple has a year under his belt to help shed the "raw" label. Darian Thompson's return at FS should help the defense cut down on big plays given up. Romeo Okwara should get better with seasoning. I think it's not unreasonable to expect Adams and Goodson to contribute more this upcoming season. Finally Perkins and his 4.0 yards a carry should have a much bigger role this season.
8) The team already looks like it's a contender and that's before they add talent via the draft
