He could always play special teams
OK, let’s say Jefferson, Osborn and Davis are all good in their first years. Not only that, let’s also say that Johnson, Beebe and Tajae Sharpe get better and Kirk Cousins has a great year.
If that all happens, Harvin probably wouldn’t be needed on offense, but he could still provide a role for Minnesota. Harvin has proved to be a dangerous return man at times in his NFL career. Letting him take kickoffs and the occasional punt return for the team would add a different, more exciting dimension to Minnesota’s special teams.
Harvin has 4,127 career yards on regular season kickoffs for an average of 27.2 yards per return. He also had five kickoff returns for touchdowns in the regular season. Sure, he could return to the NFL and not be as good as he once was, but it’s worth giving him a shot, and imagine if he was able to rekindle some of his old returning ability?
