If they do a good job at the Convention, they'll pick up a couple more. My picks for speakers list : Shapiro, Obama, Whitmer, Walz, Probably Cyburn. maybe Newson (to talk about Harris CA experience), Klobuchar to talk about Walz. Have Biden do a video address one day and show up live for a walk on later in the week. They'll get flack for Biden on video - but more important he give a good speech than risk a down day for a live one.
