Tempers flare when things don't go as planned in the National Football League.

That was fully on display Sunday, when the New York Giants scored a 27-20 home victory over the Dallas Cowboys. Things got so heated that Cowboys defensive end — and hot head— Greg Hardy had to be separated from star wide receiver Dez Bryant on Dallas's sideline during a heated exchange.

Bryant simply brushed off the incident as part of football afterwards, but during the sideline flare up, Hardy slapped a clipboard out of one of the Cowboys' coaches hands and teammates had to step in to separate the two.

And Hardy's foul mood would only continue during his postgame interview, in which he channeled Marshawn Lynch, only offering, "no comment, next question" several times, cutting the session short.

Hardy's antics sparked an NFL Week 7 theme of craziness. Here are other plays that supported the theme.

Stefon Diggs Makes Leaping Catch Look Easy

Stefon Diggs is the real deal. For the second straight week, the Minnesota Vikings wide receiver has dropped jaws. On Sunday, he made a leaping 36-yard touchdown reception to help the Vikings score a 28-19 victory over the Detroit Lions. Unbelievable catch...one of six receptions Diggs hauled in via a 108-receiving yard performance.

Amari Cooper Runs Chargers Dizzy

Oakland Raiders rookie wide receiver Amari Cooper continues to impress, running past, around and through the teeth of the San Diego Chargers defense on an electric 52-yard touchdown reception. Seeing this play is believing. The Raiders held on to win 37-29.
