Chiefs GM Brett Veach's most perplexing roster decision could come back to bite him after Mike Pennel joins conference rival

Pennel previously played for Bengals defensive line coach Jerry Montgomery during their time together with the Green Bay Packers from 2015-16. Not only is it a blow that Pennel won't be returning to K.C., but so is the fact he signed with a conference rival such as the Bengals.

He will likely be fast tracked to Cincinnati's 53-man roster, where he'll join All-Pro defensive end Trey Hendrickson along the defensive line. The Chiefs acquired Derrick Nnadi, who spent the first seven years of his career in K.C., in a trade with the New York Jets following the conclusion of the preseason.

He is already listed as a starter on the Chiefs' depth chart , and projects to get plenty of work on first and second down situations. Nnadi will play alongside All-Pro Chris Jones. Also in the mix at DT is rookie Omarr Norman-Lott and veteran Jerry Tillery. K.C. has three on its practice squad in Marlon Tuipulotu, Zacch Pickens, and Brodric Martin.

Defensive ends Charles Omenihu and Mike Danna also have the versatility to play DT, so expect to see them rotated inside periodically. The Chiefs are also banking on the development of Norman-Lott. He is entering the league with a nice pass rush skillset, and has put some weight on to become more of a force against the run.
