Is anyone else sick of this,"Trade [insert name] for [insert name]?" This isn;t Madden. You cannot get your dream player on the field in this day and age. Heck, we don't know if we can afford to keep Hamlin and Flo, how we gonna afford All Pros at every positioon.
Spears is a solid starter. He does his job well. Is he the all wrold, beat all 3-4 DE? Nope, but he is a solid contributor that will stop the run.
Carpenter has not had the opportunity to play. His rookie year, he showed good things. Last year, he was hurt in preseason and Wade really didn't give him a chance. Spencer is in the same situation. Ellis is ahead of him in the rotation. He likely won't start next year. If Carp is a bust and only worth a fourth, then after next season, so is Spencer.
The only thing we really should be considering to trade is draft picks. I would gladly give our #28 for Roy Williams. We have to get a solid receiver somewhere. If we use #28 on a rookie WR that won't contribute for two years, then we won't be any better. We are better off getting an established player with experience.
To win the Super Bowl next year, we need a proven receiver, a starting caliber CB and a back up RB, if Jones leaves. Then we need depth after that. Another DE won't put us over the top. Replacing Spears may be harder than some of us think.
