Evening AFC West notes

The Kansas City Chiefs have reportedly signed second-round pick guard Jeff Allen. He would be the fifth of eight Kansas City picks to sign. Allen will likely be a key backup this season.

Tight end Martin Rucker said he has signed with the Chiefs. He tried out for the team last weekend. He was a draft pick in Cleveland four years ago when the Browns were coached by current Chiefs’ coach Romeo Crennel.

John Elway explained to Broncos’ fans why he took Arizona State quarterback Brock Osweiler in the second round of the April draft.
