Josh Rosen is that kid in college who studied abroad for a year and thinks he's smarter than everyone. He's 21 and a little too gabby but he's a good kid. He'll mature as he gets older.
You can kinda tell he wants everyone to know how smart he is. As he gets older he won't feel that need anymore. Take him at #4, #6, #7, #8, #9, #10 just take him. He's instantly the second best QB we'd have in our history the moment he signs his contract.
