We track the Kansas City Chiefs NFL Draft visits and workouts each year and our list for this year is below. Teams talk to almost every player at the Combine (formally and informally) and send a scout to most of the pro days so I'll be focusing more on the visits and workouts rather than the Combine interviews and pro days.
There are draft visits to the Chiefs facility and there are workouts. Players that visit the Chiefs facility do not physically work out -- those are just visits where you can meet the coaching staff or front office. The Chiefs can work a player out someplace else, such as before or after their pro day on campus. Teams can have 30 players visit their facility; they can work out as many as they want.
Just because a team has a player visit doesn't necessarily mean they're interested in them. Often the Chiefs will use their visit on small school players that they haven't gotten a chance to know throughout the draft process. Or they could be looking at players that were injured and need a medical checkup. Players with draft question marks (hi, Robert Nkemdiche!) will also potentially require a visit.
We don't have a complete list of the players the Chiefs visit with or work out because they don't give that to us. However, we do know some of those players from various reports. Here's what we have so far. Click the link for the source.
