Welcome to the NFL, rookie.
The Kansas City Chiefs rookie minicamp officially starts today with the Chiefs eight draft picks, 15 undrafted free agents and other tryout players coming out to Arrowhead for a string of practices.
There are three days of practice this weekend and two of those days -- Friday and Sunday -- are open to the media, which means you'll be seeing a few seconds of practice on the local news and hearing the rookies talk about their first weekend in the NFL.
The players won't be working in full pads so this won't be a hard-hitting practice or anything like that (which is the theme of the offseason). This will be the first time many of them have been to Arrowhead so little things like figuring out where the meeting rooms are and just meeting the coaching staff is important.
It's also a chance to spend time with the coaching staff learning the playbook. Regardless of where these rookies played in college, there will be a steep learning curve in picking up an NFL system, which includes new terminology, concepts and increased responsibility for each. No one knows the schemes and methods involved better than the coaches. Having a chance to pick their brains is critical for rookies.
