The New York Giants are coming off of a 2018 campaign in which they won just five games, and going into 2019, it doesn't look like the Giants will be all that much better.

New York traded away Odell Beckham Jr. this offseason, and its decision to draft Duke quarterback Daniel Jones in the first round obviously signals that the franchise is prepared for a rebuild.

Eli Manning will begin the season under center, but if the Giants struggle early on and are knocked out of playoff contention within the first couple of months, you may very well see Jones get some action.

While New York probably isn't going to be making any noise regardless, there remain some concerns for this squad heading into 2019, and here are three of them.

3. The Pass Rush

The Giants ranked second-to-last in the NFL with just 30 sacks in 2018, and it's hard to see where the improvement is going to come from this year.

While they have some nice young pieces like defensive end B.J. Hill and rookie defensive tackle Dexter Lawrence, New York does not have any proven pass rushers on its roster, meaning it will likely rank at the bottom of the league in sacks yet again in 2019.

This is not something we are accustomed to seeing from the Giants, as they boasted a dominant pass rush in both of their most recent Super Bowl wins during the 2007-08 and 2011-12 campaigns.

But, this New York squad hardly even resembles those teams, so I guess it shouldn't come as too much of a surprise.

2. The No. 1 Receiver

With Beckham gone, the Giants obviously need someone to step into the No. 1 receiver role. It's not like Beckham is merely out with an injury like the 2017 season, either. This time, he is gone for good, and New York needs to adjust.

The first wide out in line to take his place is Sterling Shepard, who has been a reliable No. 2 receiver for the Giants since entering the league in 2016. But is he ready for a No. 1 role, and does he even have the ability to be a dependable No. 1 receiver?

Of course, there is also veteran Golden Tate, but with his best days behind him, it's hard to imagine him snatching the top receiver role.

Chances are, it is going to have to be Shepard, who has an awful lot to prove. He hauled in 66 receptions for 872 yards and four touchdowns this past year, but he will have to be quite a bit better in 2019.

1. The Offensive Line

That brings us to the Giants' biggest issue.

While New York's offensive line did show some improvement during the second half of this past season, Pro Football Focus still had the unit ranked 21st overall, as Manning was getting rocked by opposing defenses through much of the year.

Nate Solder has been a big disappointment for the Giants at left tackle, and he was supposed to be a big addition for them two years ago.

New York did swing a trade with the Cleveland Browns for guard Kevin Zeitler, which should certainly help, but there is no question the entire offensive line as a whole remains a huge question mark.
