Is USC poised for an amazing finish to the 2015 recruiting season?

On Friday, USC landed a commitment from Brighton (Salt Lake City, Utah) linebacker Osa Masina, a five-star recruiting according to 247Sports.

It is the start of what likely will be an incredible finish to the Trojan's 2015 recruiting season.

Fellow Utah five-star linebacker Porter Gustin will announce his college decision a week from today, and USC is the 247Sports Crystal Ball favorite.

On National Signing Day, USC is favored to land commitments from three other five-star defensive prospects: John Houston and Rasheem Green of Serra (Gardena, Calif.), and Iman Marshall from Long Beach Poly (Calif.).

If USC lands those three recruits, it would likely trump even last year's fantastic finish, in which USC nabbed commitments from Adoree Jackson, JuJu Smith and Damien Mama.
