Bills-Eagles Trade?

There's growing speculation that the Eagles may be targeting the Bills #11 pick for a draft day trade. Philly wants an offensive tackle. The three teams picking after the Bills...Denver, Carolina, Chicago...all have needs at tackle. To get the guy they want, the Eagles may have to move up from #19 to the Bills pick. Now, what would it take to go there? The draft trade chart shows a 310 point difference in the picks, roughly equal to a late second round pick. Or, could Andy Reid dangle cornerback Lito Sheppard. He's on the block due to the signing of Asante Samuel. Would the Bills be interested? That would fill a need at corner. Plus, picking a wide receiver like Devin Thomas at #19 makes a lot more sense than taking him at #11.
Stay tuned. It makes too much sense to ignore.
