The New York Giants are coming off of a 2019 campaign in which they won just four games, but there actually is some excitement surrounding the team heading into 2020.

Daniel Jones has established himself as the Giants' quarterback of the future, we already know Saquon Barkley is a stud and Dave Gettleman has done a fine job improving the rest of the roster this offseason.

But how much better has New York actually gotten?

Here are the three biggest questions pertaining to Big Blue as the 2020 season approaches:

3. Where will the pass rush come from?

To Gettleman's credit, the Giants made a concerted effort to bolster their defense this offseason, signing the best cornerback on the free-agent market in James Bradberry and inking linebacker Blake Martinez.

But you still have to wonder where New York's pass rush will come from. The Giants didn't have much of one in 2019, ranking 22nd in the NFL with 36 sacks.

Is there anyone on their current roster who can consistently get to the quarterback? Doesn't seem like it.

New York could always bring back Markus Golden, who paced the club with 10 sacks this past season, but the fact that he is still on the open market indicates that his asking price may be a bit high.

And yes, the Giants did bring in Kyler Fackrell, who posted 10.5 sacks with the Green Bay Packers in 2018, but he has logged just 16.5 sacks overall in four seasons.

2. Can Daniel Jones correct his fumbling issue?

For a young quarterback in the modern era, Jones checks just about every box. Solid arm. Accurate thrower. Athletic. Can make plays with his legs. Good poise.

His passing numbers in his rookie campaign reflected that, as he threw for 3,027 yards, 24 touchdowns and 12 interceptions while posting a passer rating of 87.7 in 12 starts.

However, there is one glaring issue he needs to correct: ball security.

Jones fumbled 18 times in 2019, something that can absolutely torpedo his career if he doesn't get better in that area. To be fair, that is definitely a fixable issue. Eli Manning also had a similar problem early on, and he proceeded to remedy it.

Whether or not Jones follows Manning's path of improving is the main question. If Jones can get this down, he has a very bright future ahead of him.

1. Will the offensive line provide enough protection?

Since 2013, the Giants' offensive line has largely been an abject disaster. It showed signs of considerable improvement throughout 2019, but it is still clearly a work in progress.

Gettleman went to work on repairing the line this offseason, selecting University of Georgia tackle Andrew Thomas with the fourth overall pick in the NFL Draft and then taking another offensive lineman in Connecticut's Matt Peart in Round 3.

While you have to appreciate the front office's effort to fix the problem up front, the jury is obviously out on whether or not the line can consistently provide adequate protection for Jones and Barkley.

Thomas looks like a stud, and he will probably end up moving Nate Solder over to the right side of the line, which could be killing two birds with one stone. But we'll see if everything actually works out.
