Ereck Flowers is not going anywhere, other than a new position.

The Giants have no plans to release their 2015 first-round draft pick, not even after he underperformed for three years as their starting left tackle. The new front office and coaching regime learned from the mistakes of those who came before them — they knew they could not go into the 2018 season with Flowers once again as Eli Manning’s blindside protector. On Wednesday, they ensured that scenario would not play out again, agreeing to terms with Nate Solder, the top left tackle available in free agency, on a mega-deal worth $62 million.

This means Flowers is headed to a new spot on the offensive line, and not necessarily right tackle. Depending on what the Giants do during the remainder of the free-agency period and later in the NFL draft, Flowers could find himself at right tackle or competing for one of the starting guard spots, even though he has never played guard.

For Giants fans, it may seem as if Flowers has been around forever or far too long, but, incredibly, he does not turn 24 until April 25, one day before the start of this year’s draft. He is durable, starting 46 of a possible 48 games in his three seasons. Plus, he is relatively inexpensive heading into the final year of his contract with a 2018 salary of $2.397 million and a salary-cap hit of $4.5 million — nothing extraordinary for a starting player.

There are several quality guards available in the draft and there is every reason to believe the Giants, with their second-round pick (34th overall) can find an interior lineman able to compete immediately for a starting job. If that is the case, Flowers moves over to right tackle — where many scouts and talent evaluators believe he should have been all along — and he is unburdened as far as dealing with the opponent’s best pass-rusher on a weekly basis. If the Giants uncover a right tackle in free agency or early in the draft — a less likely scenario — Flowers will be given a shot to compete for a starting job at guard.

At present, the Giants have John Jerry on the roster as a returning starting guard and Justin Pugh is an unrestricted free agent. At 6-foot-6 and 325 pounds, Flowers looks more like a tackle than a guard, but players with his size and bulk have made the transition. Either way, Flowers as the left tackle is a thing of the past for the Giants.
