Consider they know a lot more about the physical condition of many of these players that are being let go. They know what their level of play was and what it is today and can see trends. For example: Adams back. A definite problem at one time and may be getting worst. Maybe he's spending more time in the tub? Maybe the team trainer has an evaluation that is not too good on Adam or Willie. Maybe Bill has seen things in Willies play last year that indicates he is slowing down. I sure noticed how tired he looked towards the end of the season. What I am saying is these guys have so much more information that we fans just need to trust their decisions when it comes to letting our favorite fans go. Just maybe Bill and Scott deserve some breathing room. As to why no replacement? Maybe they are working under constraints that we are not aware of.
