Custom on-field style jersey. Everything is sewn on, size XL. Hand-signed and inscribed in black felt-tip pen by Jackie Slater (HOF). In 1980, Slater was a part of an offensive line that surrendered just 29 sacks and helped the Rams' offense finish second in the NFL in total yards gained with 6,006. In 1983, he and the Rams offensive line demonstrated their versatility when they allowed a league-low 23 sacks while also paving the way for Eric Dickerson's rookie rushing record of 1,808 yards.
