I wouldn't feel comfortable speaking in such absolutes but that's just me. You may be right...maybe Sage isn't going anywhere, but your reasoning doesn't mean anything given recent history.
Seems like I remember some saying the same thing about Carr a year ago. Something to the effect of 'we will not get rid of Carr for an unproven back-up QB'.
Well, as we all know, not only did we get rid of him and acquire an unproven back-up, we gave up two 2nd round picks for the unproven back-up...mainly b/c of the talent evaluation of Smithiak which led them to believe Schaub was worth the risk. Now, we have this current scenario which leads many of us to believe we acquired Gray in order to deal Rosenfels. It is a risk letting go of a capable back-up, but apparently Smithiak feels that Gray can step into that role AND we can get an extra draft pick.
I guess what I'm saying is that I trust the current regime to make the correct decisions...and IMO it seems that they may be leaning towards trading Rosenfels. If so, judging by our front office's track record, I believe they will make the correct call.
