Don't know who this guy is. Mainly because I only pay attention to black receivers. But here's what I dug up on Hartline: 6'1, 195 lbs. He's not all that fast, but he's athletic, intelligent, has good build and good hands. He's known for his blocking and his work ethic, which likely means he's a special teams guy. He also compares himself to Colts receiver Anthony Gonzalez. Not sure if it's because Gonzalez is a former Buckeye, or because he's white. I think the Fins may have reached for him with such a high pick, but I'm typing this in my underwear at 1:00 in the afternoon, so what the hell do I know.
Update: Palm Beach Post has a quote from Hartline:
Hartline said he also brings a presence on special teams, a key to getting on the field for a Dolphins wide receiver.
"I love it," Hartline said. "I like cracking heads. It's a lot of fun."
