KeiVarae Russell tweets he signed with the Chiefs

The Kansas City Chiefs 2016 draft class appears to be all signed, sealed and delivered. The last remaining draft pick to sign - third round pick CB KeiVarae Russell - tweeted that he has signed with the Chiefs.

There was some talk that third round picks were harder to sign this year, as ESPN's Mike Reiss pointed out.

One NFL salary cap man relayed that third-round negotiations have proven to be more challenging than other rounds in recent years. The reason is that first- and second-round picks can receive a maximum of 25 percent allocation of a team's rookie salary cap, but because the third round doesn't max out at 25 percent, there is often debate over what the correct percentage should be. That has created a situation where the third round has been the spot in the draft where some agents are pushing for more annually, such as the inclusion of workout bonuses in the deals.

That makes nine draft picks signed. That was easy.
