My take:
"Due diligence" at the "23rd hour" reads like an oxymoron

I believe the Bills shopped McCoy today but due diligence would've been exploring trades once Singletary showed signs of rapid development

Instead teams refused to bite on a player who BUF clearly didn't want https://t.co/PCDhzMRG7M
