TT - Gold Cup Goalscorers

In the nine Gold Cup tournaments and four championships to date, there have been 36 different U.S. goalscorers. So we'll make it simple - especially since you will have one hand on a burger while thinking through this:

a) Who has the most all-time goals?
2) Who has the most goals in one game?
3) Who has the most career goals in the Gold Cup on this roster?
