Leading into the start of training camp (rookies report July 22, veterans July 24) The Post will provide Giants fans with a position-by-position look at the roster.

The Giants made good on their succession plan by taking Daniel Jones with the No. 6 pick in the NFL Draft. So now we know who gets the ball next from Eli Manning. When that handoff arrives will be the weighty decision — one that will hover over this franchise until it happens. Given the struggles of the team and the offense the past few years — Manning operated behind a lousy offensive line, mind you — is this a short leash for the beloved two-time Super Bowl MVP? Fans who were lukewarm about Jones as a prospect were apoplectic when he was taken so high, with the Giants also owning the No. 17 pick. In time, he will get the chance to change the minds of his doubters. For now, the 38-year-old Manning tries to stave off the inevitable, one pass and one game at a time.

Key returnees: Eli Manning, Alex Tanney, Kyle Lauletta

Key additions: Daniel Jones

The rundown: There is nothing about playing the position that Manning does not know. He will be far more advanced working in year No. 2 of the Pat Shurmur offensive system and is in perhaps the finest shape of his career, which is saying something, considering his always-exemplary fitness level. He needs to produce now, though, as his protection will be improved and he has the wondrous Saquon Barkley in the backfield. Jones appears to be a quick study and Shurmur (and offensive coordinator Mike Shula) heaped praise on the rookie every chance they could. Clearly, the organization believes Jones is the man for the future. When that arrives depends on Manning’s ability to steer his team to many more wins than the past two seasons.

Key camp battles: Coach Pat “I’m not trying to be cryptic’’ Shurmur had some fun dancing around the Eli vs. Daniel competition that really might or might not exist this summer. Shurmur’s insistence Jones is on track with “the goal of being ready to play Day 1’’ sounds as if Manning can be overtaken this preseason. In truth, it is Shurmur’s coach-speak for declaring what he sees as obvious: Every player is preparing for the opener. Unless Manning suffers a sudden age-based decline and Jones’ development is impossibly rapid, Manning starts and Jones waits. The real camp battle is Tanney vs. Lauletta – unless Shurmur opts to get rid of both and go with only two. Lauletta (23) is younger and should have more upside than Tanney (31), but Tanney has the experience and would be more valuable as a sounding board.

The verdict: There is quite a split in the fan-base. Some wanted to thank Manning for his years of service, the two Lombardi Trophies and his professional demeanor and bid adieu. Others see the roster erosion around Manning as the real culprit. No one seemed especially pumped about Jones when he came aboard. Manning lived through a seismic shift as a rookie in 2004 and knows he must get out of the gate quickly. His team was 1-7 at mid-season the past two years; a repeat of that ineptitude will prompt the powers that be to make the move to Jones.
