Running back Kevin Smith is working hard this offseason so that he can be Detroit's "lead dog" this fall. "For me being in shape and ready to go is a must. It's not even an issue. I feel I'm a tempo-setter, so I have to be in great shape and looking and feeling good for this training camp," Smith wrote on his web site - Smith34.com. "I feel I have the mentality that I'm the lead dog and I'm going to set the tempo. It's a mentality I like to take on and you can do it if you have the killer instinct."
