"Top Fantasy Football Waiver Wire Stashes for Week 4: Calvin Austin, Marvin Mims, Luke Musgrave"

In fantasy football, it's important to have backup options in case of injuries or underperforming players. Three potential roster additions for Week 4 include Calvin Austin (WR - PIT), who is emerging as a value option in the Steelers' passing game; Marvin Mims (WR - DEN), who leads the Broncos in receiving yards and is a high-risk, high-reward stash; and Luke Musgrave (TE - GB), a rookie tight end with growing potential in the Green Bay offense.
