Chiefs add linemen Ndukwe, Alleman

New Kansas City Chiefs general manager Scott Pioli kept it in the family as he tried to upgrade the Chiefs' offensive line.

Pioli acquired two offensive linemen from the Miami Dolphins for an undisclosed selection in the 2010 draft. The Dolphins are run by Bill Parcells, who is Pioli's father-in-law.

The Chiefs acquired guard/tackle Ike Ndukwe and guard/center Andy Alleman. Ndukwe is expected to push for a starting spot at guard or tackle.

He was a starting guard for the Dolphins last season but was moved to tackle this year.

Alleman is expected to provide interior line depth. Alleman is a third-year player from Akron. He started four games last season for Miami.

The Chiefs' offensive line has been a work in progress since the offseason and it has been somewhat shaky this preseason. Thus, the pursuit for stability led to this trade.
