New quarterback Marcus Mariota has already impressed his new Tennessee Titans teammates in training, according to linebacker Zach Brown.

The 21-year-old was the second overall pick in the NFL Draft earlier this month and has apparently made a big impression in training.

Brown told The Tennessean: "One time he took off. I was guarding Delanie [Walker] and I turned around and I was like, 'Where is he?'. He is fast. He impressed me. He is still a rookie and he has to learn, but he is a cool guy. I haven't seen him get frustrated yet."

Mariota played college football for the Oregon Ducks.
