That depends on how the season unfolds
That depends on any number of variables, most importantly how the season unfolds for the Giants.
As much as the Giants have shown their willingness to prepare for the future by drafting Jones No. 6 overall, given the loyalty ownership and GM Dave Gettleman have shown to Manning it seems unlikely they will be in a hurry to shove Manning aside.
If Manning is playing well, or well enough, and the Giants continue to have a realistic chance to reach the playoffs, it’s hard to envision the Giants pulling a Kurt Warner on Manning.
Still, Jones is going to play … eventually.
Albert Breer of Sports Illustrated has charted quarterbacks drafted in Round 1 since 2008. Here is what he found:
From 2008 through last year, 32 quarterbacks went in the first round. Fifteen of them started in Week 1 of their rookie year.
Seven more were starting inside the first four weeks, taking the number to 22 of 32 quarterbacks. Two more on top of that were starting Week 5, taking the number to 24, or three-quarters of the group. Some of those guys (Blake Bortles, Mitch Trubisky) were in despite strong declarations that they’d be redshirted.
Only two were really redshirted. One was Locker, who sat behind Matt Hasselbeck with the Titans as a rookie and got his first start in the opener of his second season. The other was Mahomes, who watched Alex Smith from the sideline for most of 2017 before getting the start in the Chiefs’ meaningless regular-season finale. The common thread between the two? Both were on contenders, which made sitting the younger quarterback more or less a non-issue.
There is really no way to know how the 2019 season will go for the Giants. Unless Manning and the Giants are in the midst of a turnaround season, though, recent history tells we will probably see Jones … eventually.
