It’s being reported Ertz is being released to explore his options. Not sure how he’s looked this year, but feels like it could be worth kicking the tires on if he’d be better than irv.

Ertz requested to be released likely hoping he can get back to Philly with Goedert still injured/coming off injury. Backup plan is probably Baltimore and maybe retirement .
