It's an exciting -- although not new -- development.
"There's a tremendous opportunity there and we've had the privilege to play together in high school, college and now the NFL," Derek said Thursday in an introductory presser, via TribLive.com. "There's so much more that goes into it than that."
"We're extremely excited, but it's not the main reason," he said. "There were so many positives."
A noted special teams contributor in addition to his fullback role, Derek is also a fan of the aura that surrounds one of the NFL's most storied franchises.
"It's a hard-working, blue-collar, tough-nosed organization," he said. "That kind of fits into the way I was raised and the way I try to play the game."
And so Derek finds himself changing teams and time zones, reuniting with his brother and in a situation that he believes he was made for.
