NY Giants Co-Owner -- I'm Rooting for 'Concussion' ... I Hope It Educates, Empowers

NY Giants co-owner Steve Tisch says he's still cool with Will Smith -- and is actually rooting for his new movie "Concussion" to do well ... despite the fact it's about a doctor who takes on the NFL.

The movie has been getting a TON of buzz -- with the trailer suggesting the NFL hatched a diabolical plot to intimidate a doctor into hiding evidence about the real dangers of football related brain trauma.

Tisch says he hasn't seen the movie yet, but says he's not even mad about it at all -- "I hope the movie not only entertains, but educates and empowers."

Tisch also says the NFL isn't trying to hide anything -- in fact, he's adamant the league is very proactive when it comes to head injuries.

"There's a very high level of consciousness about concussions in the NFL," says Tisch ... who claims the league is doing everything in its power to educate the players.
