Anthony Campbell has emerged as the Green Bay Packers' biggest surprise from 2026 NFL training camp after a standout summer. Anthony Campbell arrived at Green Bay Packers training camp with a roster number, extraordinary length, and little evidence that he belonged in a crowded NFL defensive line rotation. The Seattle Seahawks signed Campbell after the draft, waived him at the end of training camp, and briefly retained him on their practice squad. No Packers player has reshaped his outlook more dramatically this summer. Campbell entered camp fighting for relevance and now heads into the preseason with a legitimate chance to make the roster, making him Green Bay’s biggest surprise from 2026 NFL training camp.
