Everybody knows that fanbases coming down hard on athletes who are underperforming is just a part of sports. But booing a player who has yet to take even a preseason snap? That's extraordinarily shameful and embarrassing.

For some reason that we can't quite fathom, New York Giants rookie quarterback Daniel Jones is ALREADY getting cast as public enemy No. 1 in the Five Boroughs.

The No. 6 overall pick in the NFL Draft was at Yankee Stadium Monday night watching the Bronx Bombers take on the Tampa Bay Rays, and he was ferociously jeered by the crowd.

So, so distasteful. This kid has done nothing wrong. Giants fans likely aren't even upset with Jones -- and those who are cannot be considered true fans -- but at the franchise's direction under general manager Dave Gettleman.

But sure, let's take it out on a 22-year-old kid still working his tail off to learn as much as possible under the wing of Eli Manning. And this all comes after Jones was drawing praise from Giants teammates and reporters thanks to some impressive signs in offseason workouts.

New York fans never like to be compared to their brazenly demanding counterparts in Philadelphia, but booing a rookie quarterback before training camp even starts is very much on the same kind of level. Keep the boo-birds caged until Gettleman and Co. are shown on the video boards at MetLife Stadium. Give the kid a chance to prove his worth.
