What does it mean?

As noted today in Dejan Kovacevic's Notebook in the Post-Gazette …

Kyle Stark, director of player development, said (left-hand pitcher and 2007 first-round draft pick, selected by Dave Littlefield over Matt Wieters -- JPPBs editorial note, ahem) Danny Moskos will start again someday but that management wants to lessen the workload in his first full professional season.

"This is not a future role change," Stark said. "We want him to work on being athletic, being aggressive and attacking the zone with this best stuff."

What does that mean? JPPBs never heard a front office type, scout, coach or manager say of a pitcher, "We want him to work on being athletic."

To the contrary, many, many pitchers today and throughout baseball history have been downright unathletic, even fat (David Wells, Mickey Lolich) , yet were able to pitch effectively.

When Kyle Stark says, "We want him to work on being athletic," does that mean they want him to begin training for Olympics gymnastics? Cirque de Soleil? Steelers training camp? Spring training?

Are they saying Moskos is out of shape?
