You guys do make some good points. We have lost a lot in Fletcher, Clements and Willis.
Reading in between the lines, however, the only one that we really wanted back was Clements (as evidence by putting Willis on the trading block and Marv making his comment about "attacking" linebackers in contrast to "pursuing" linebackers).
We want to go with the two running back system, which worked pretty well for Indianapolis, Chicago, New England, New Orleans, etc. So, in our coach and GM's eyes we will be upgrading our running back spot. You also have to wonder if Crowell was being groomed to take Fletcher's spot in preparation for his impending free agency. The 8 or 9 games he played in he was extremely impressive. Jauron and Levy also refer to him as an "attacking" linebacker so you have to think that they may believe he would be an upgrade over London.
The only position I can't defend is the cornerback spot. Clearly, McGee is not ever going to be a #1 cornerback. At this point we should be hoping he pans out as a solid #2. Youbuty has great upside, but he and Kiawaukee Thomas can't even be compared to Clements.
Very early to do a biggest winners and losers segment on ESPN, but even if you want to I don't think these losses (except for Clements) will be that big of a factor. My humble opinion of course.
