Congrats to both of them.
Higgins is a Jr. so this 'ship will affect the numbers for the 2011 class and/or the attrition numbers needed by February 2011. With the current commits, that attrition number is currently at 5. Any additional commits or if someone like Allen were to redshirt this year then that number would increase.
Gold is a senior and will not affect any of the 2011 or future numbers.
