The Facts: Howard and Matt Breida figure to share carries, unless OC Chan Gailey believes one is a better matchup in a particular game, or has the hot hand. Breida has averaged five yards per attempt in his career, while Howard is at 4.3. But Howard is a powerful man and should be the top choice anywhere near the opposing goal line.

Diehards Line: Breida was clocked at 22.3 miles per hour on an 83-yard touchdown for the 49ers last season. No player was clocked faster. And Gailey will attempt, obviously, to get Breida into space. If he, Albert Wilson and Jakeem Grant are all on the field together, that’s Chiefs-type speed. But does Howard, at 25, regain the bulldozing form he demonstrated earlier in his career with the Bears? Does Breida, also 25, capitalize on increased opportunities in Miami, and present as a solid pass blocker? These will be questions that must be answered during training camp and we'll be watching for the answers.
