The last thing any team wants to see within the first few games of the season is a star player falling victim to a long-term injury. It kills momentum in a way. With any injury, you're ready with the "next man up" mentality to quickly move on, but the loss is still deflating. Teams have their plans for the season, players have their goals set, you're trying to figure out this year's identity, and you lose one of the key players in creating that identity.
In the second game of the season, the Green Bay Packers lost WR Jayden Reed to a broken collarbone.
