​Bill Belichick has used some trickery on the field in the past, but it's nothing like this. 

At the NFL Rookie Premiere a couple weeks ago, rookies were getting their minds blown by a magician's card tricks, and their reactions are hilarious. 

​​Michael Rangel, a professional magician from Los Angeles, was at the LA Coliseum for the event.

Among the dumbfounded rookies were Deshaun Watson, Leonard Fournette, James Conner and more.

The rookie premiere is the first time the fans get a chance to see their team's newest player a game uniform and not just practice wear. Fournette, who wore 7 at LSU in college, will be donning the No. 27 for Jacksonville. 

Bengals wide receiver John Ross, after Rangel's last trick, asked him, "Do you own keys or do you just walk through the door?"

Let's hope the rookies won't be as confused when they step on the field with training camp right around the corner.
