When the Vikings first discuss their 53-man roster on Monday, they'll likely echo the aphorisms offered by some NFL decision-makers who talked with reporters on Saturday: that rosters, even after they're trimmed for the start of the regular season, are never set in stone.
The group of 53 the Vikings put together on Saturday, following a series of 22 cuts before a 3 p.m. deadline, seems almost certain to change: They kept seven receivers, a year after putting just four on the initial 53, and retained 11 defensive linemen. By contrast, the only two safeties on the Vikings' roster are Harrison Smith and Anthony Harris, who figure to be backed up by an acquisition in the coming days.
