It's time to move onto the guys I wouldn't stress about trying to keep.
Here's the full list of the Chiefs (expected) unrestricted free agents: NT Ron Edwards, DE Shaun Smith, WR Terrance Copper, C Casey Wiegmann, S Jon McGraw, LB Charlie Anderson, WR Kevin Curtis, CB Travis Daniels, LB Mike Vrabel, FB Tim Castille, OT Ryan O'Callaghan, LB Corey Mays, TE Leonard Pope, C Rudy Niswanger and QB Brodie Croyle.
Not in a rush to keep these guys: LB Charlie Anderson, WR Kevin Curtis, FB Tim Castille, LB Corey Mays, and QB Brodie Croyle.
Nothing personal against most of these guys but they A.) didn't stand out last season or B.) aren't familiar enough with the system or C.) aren't the best backup options anymore.
Anderson didn't distinguish himself much last year and rarely saw the field -- two games. I'm not sure why that would change in 2011. The Chiefs can find a younger option with more potential to fill this role.
I can see an argument for Curtis but he's in the same position he was when he was signed late in the 2010 season with not knowing much of the offense. Plus, his age, turning 31 years old next week, isn't desirable.
I can also see an argument for Castille and Mays but I think the Chiefs have better options already on the roster.
And then there's Croyle. He's a quarterback so he gets a lot of attention, even as a backup, but he's clearly not the answer for the Chiefs. QB Ricky Stanzi is in the house, and the Chiefs can sign another veteran backup and be done with it.
