According to Charlotte paper

[Pete]

Mike Mitchell is drawing interest from the Eagles during the "Legal Tampering" period.

Additionally, Birds 24/7 reporting that price for Bengals DE Michael Johnson went beyond what Eagles were interested in paying.

Looks like defensive upgrades are what they are looking to do early in FA

same things being said on Twitter

Don't know much about Mitchell but Johnson is a pretty good pass rusher

Edit: Looks like Johnson won't be happening
