This pretty much says it all... People act like every signing is strictly for the starters but fail to realize that you have to build a complete team and have depth. As a team you can not afford to have high priced backups and have to take players like Cook who are versitle and can play at multiple spots if a starter goes down. It is money well spent and sometimes with these guys a new coach can fix a flaw and help them better themselves.
The problem is he can't play any of these positions well.
