McCarthy has taken around one-third of the first-team snaps at training camp so far, according to ESPN's Kevin Seifert.
The Vikings have divided snaps, as promised, but with Kyler Murray getting significantly more work than McCarthy. That's no surprise given McCarthy's performance last year, but the team does still seem to have some interest in developing him. The report notes that McCarthy has spent much of the summer leading Minnesota's second-string offense against the first-string defense, with mixed results. Murray remains a strong favorite to start Week 1.
