Vikings executives watched Carson Wentz on Monday night and — like anyone with eyes — realized, “Yeah, we need a quarterback.”

Minnesota has made calls about quarterbacks ahead of Tuesday’s 4 p.m. trade deadline in a notable development, according to NFL Network.

Colts starter Daniel Jones, for-now Raiders starter Kirk Cousins and 49ers backup Mac Jones have all been floated as possible trade options.

The Vikings (6-2) have a championship-caliber defense but don’t have a reliable starting quarterback, leaving the team in a massive bind.

Kyler Murry has been a disappointment and missed Monday’s game with a hamstring injury that some speculated may have been a soft benching.

Wentz started Monday’s 23-6 home loss to the Bills and he gave Ravens undrafted rookie Joe Fagnano a run for the worst performance of the season.

The veteran completed 8-of-25 passes for 81 yards and two interceptions, wasting a strong effort from the defense before it finally wore down.

With every NFC North team sitting above .500, Minnesota clearly realizes that it will struggle to stay afloat without better play under center.

Vikings star receiver Justin Jefferson, who had another quiet night, didn’t answer directly when asked whether Minnesota needs a quarterback trade but hopes things improve.

“Not sure,” he said. “That’s on (general manager) Nolan (Teasley), that’s on (coach Kevin O’Connell). That’s their job,” Jefferson said after tallying three catches for 58 yards. “My job is to continue getting open, be the leader of this team. Come next week, hopefully things change.”

The question is whether there are any difference-making quarterbacks available and if the Vikings will meet the cost since teams know they are desparate.

The Colts told Daniel Jones they won’t trade him, per NFL Network, but every player has his cost and Indianapolis needs picks for its rebuild.

The Raiders started hot with Cousins but have lost five of six, starting the clock for when No. 1 pick Fernando Mendoza will get the keys to the offense.

The Vikings obviously have a rapport with Cousins from his six years with the franchise from 2018-23, but he’s not a long-term answer at 38.

Mac Jones is young and has shown he can be a starting-level quarterback, but there are questions about whether the 49ers would help a contending NFC team.

The Vikings’ search for a quarterback is now one of the top trade deadline storylines along with Jonathan Taylor’s availability.

Minnesota’s need for a quarterback is especially glaring since it faces the rival Packers (6-3) at Lambeau Field on Sunday in a game with major NFC playoff implications.
