Arnold said those early morning sessions with Townsend, Lions passing game coordinator and defensive backs coach, have been invaluable for him. They go over the routes he'll probably see that day in practice, cleaning up technique issues, and going over film from his rookie season.
Townsend's main message to Arnold has been all about the football - get your hands on the football and hopefully secure Arnold's first career interception.
Arnold's veteran teammates have also been a big influence on him.
"Those guys literally helped me take the biggest jump," Arnold said. "Just being on me and making sure I'm a professional. Grooming me to be a leader. Amik (Robertson) going into what, his sixth year? D.J. (Reed) going into his seventh or eighth year. I don't take that for granted. Just being able to have tremendous guys like that in the room."
