Are the Jets really "shopping" Milliner, or are teams inquiring about him? There's a big difference. I haven't seen anything to suggest that he's been made available via trade. Just that a few teams have been sniffing around, seeing if he's available.
I think trading Milliner would be a big mistake. You're talking about a guy who could conceivably be Revis or Cro's replacement in a few years. He's tremendously talented and would be a steal for any team offering up a middle round pick. I know he's had a few injuries here and there, but im still not convinced he's as injury prone as some suggest. How many games did he miss at Alabama? He played hurt in college.
What if a team offered you a pick in the top 40 right now? You'd say no thank you?
