Tough learning curve for Sveum, Ventura

Sveum: A.

Ventura: D.

You know Sveum is in it for the long haul, working to hang on to his job until the better teams are built. Ventura turned down a one-year contract extension last winter, saying he wanted to serve out this three-year contract before deciding if this is the life he wants for the long haul.

"I wonder if Robin is motivated to be a part of a complete rebuild,'' an MLB executive said. "Maybe that's why he did not take the extension. They'll be bad for an extended period. He's such a winner, this might not be something he wants to endure''

Given the job demands that require 12-hour work days and the relentless nature of a 162-game schedule, it would be easy to understand if Ventura walked away. But White Sox GM Rick Hahn needs to resolve this question as soon as possible, not after the 2014 season. If the manager is taking a wait-and-see approach, it's easy for fans to follow that example.

Final grade

Sveum: B.

Ventura: C.

That's a high B for Sveum and a low C for Ventura, who probably didn't get too many of those while attending Oklahoma State.
