The San Francisco 49ers benefited from the quick rise and fall of the Alliance of American Football, which lived a short life from its founding in March of 2018 until it’s collapse in April of 2019 after financial problems.
San Francisco ended up netting two key players from the now-defunct league, defensive lineman Damontre Moore and offensive lineman Daniel Brunskill once the league folded. While Moore bounced off and then back on the Niners roster, Brunskill would eventually be an integral piece along the team’s run up to Super Bowl LIV.
Brunskill, originally a 2017 undrafted free-agent signing of the Atlanta Falcons, ended up seeing action in 14 regular-season games for the 49ers, starting seven of them following injuries to the Niners’ two starting tackles, Joe Staley and Mike McGlinchey.
