Daniel Jones was the first to be picked and the last to sign.

But the Giants’ full 10-player 2019 NFL Draft class now is under contract after Jones and focus can turn to the next big question: How soon into his four-year deal will Jones take over for Eli Manning as the starting quarterback?

Will it be early in the 2019 season after another too-common slow start by the Giants? Late in the season, if playoff hopes are dashed? Next season, after Manning’s contract expires? Or further yet down the road?

Jones agreed to his rookie contract with the entire signing bonus in Year 1, as first reported by NFL Network and confirmed by NJ Advance Media. The Giants rookies and select veterans will open training camp Wednesday, and Jones likely will sign his deal before taking the practice field.

It is the second straight year the Giants’ waited until the day rookies report to sign their top draft pick.

The Giants used a first-round pick on a quarterback for just the third time since 1980. One was Dave Brown in the 1993 NFL Supplemental Draft and one was Philip Rivers, who quickly was traded for Manning in 2004.

Jones was the No. 6 overall pick, and it seemed most of NFL lampooned general manager Dave Gettleman for unnecessarily reaching, especially considered he picked No. 17 and No. 30 in the first round, too.

The Giants passed on highly regarded outside linebacker Josh Allen, a Montclair High School product, who could have filled a huge need. Allen went to the Jaguars, who were stunned he slipped to No. 7.

But the consensus opinion of the Giants began to change during Organized Team Activities and minicamp, as Jones displayed better-than-expected arm strength and lived up to his reputation at Duke as a quick learner.

Coach Pat Shurmur reiterated Manning is the starter, but he says Jones is on track to be ready to play by Week 1. The Giants might not have a full-fledged quarterback competition brewing during training camp, but it is clear Manning’s leash will be shorter than ever if the Giants head toward a sixth losing season since 2013.

The Giants’ ideal plan is to have Jones sit for most or all of his rookie season, which could allow for a proper send-off for Manning. But the two-time Super Bowl MVP has given no indication of his retirement plan.

“We’ve got a young player that we think is going to be an outstanding player who is getting himself ready to play,” Shurmur said.

Jones’ contract is expected to be worth $25.57 million with a $16.62 million signing bonus, according to spotrac.com. Jones could have the 10th-highest salary-cap hit on the Giants in 2019 even though the bonus is spread out evenly over the duration of the contract.

By the end of the 2021 season, the Giants must decide whether or not to exercise a fifth-year option on Jones’ contract. Quarterbacks on rookie contracts are bargain commodities compared to the rest of the market.

The NFL uses a rookie wage scale and the predetermined value decreases with each successive draft slot.

There is little room for negotiating on either side but the hold-up with first-round picks usually is over “offset language," which allows a team to save some money if they release a draft pick in his fourth season and he signs elsewhere. Without it, a player can get paid by two teams, though a released player probably is a bust.

The Giants signed their other two first-round picks, defensive lineman Dexter Lawrence and cornerback DeAndre Baker, on June 14. They waited until the day rookies reported to training camp in late July before signing No. 2 overall pick Saquon Barkley last season.
