Warren Sharp noted that Justin Jefferson is ‘iffy to be 100 percent’ for Week 1 and Jordan Addison will be sidelined for three weeks, leaving practice reps wide open. Lucky Jackson has been running with the first team throughout camp, and Sharp said the former XFL standout has enjoyed ‘a great two weeks’ while flashing repeatedly in team drills. With uncertainty atop the Vikings’ depth chart, Sharp believes Jackson could earn meaningful routes in September and is worth a late-round dart in best-ball drafts or as a DFS punt if Jefferson’s recovery drags into the opener.
