The plan, hapazardly concocted by Biff, is to ask his old employer, Bill Oliver, to "stake" him in a small business loan. "He always said he'd stake me," Biff claims.
After getting the money, Biff proposes starting, with Happy, his own line of "Loman Bros" sporting goods. On the fly, he decides that these items will be marketed at exhibition games.
In an increasingly familiar pattern, Willy blindly believes in anything his son thinks up. Even when Biff is clearly making it up as he goes along (when gently pressed by Willy, who asks if he knows what he's doing, Biff half-heartedly replies, "I guess so.") Willy's over-the-top response is, "You know sporting goods better than Spalding!"
Willy's irrational exuberance paired with Biff and Happy's delusions about their potential will cause their scheme to go the way most get-rich-quick scams: down the drain.
