Jurors disagreed.
They found Wyatt guilty on all counts, including the murder of 10-year-old Micah Tennant.
Wyatt, 35, admitted on the stand that he brought a loaded gun to the Nov. 15, 2019, game as Pleasantville hosted Camden.
He saw Ibn Abdullah there, who had already shot at him less than three weeks earlier in Atlantic City. Abdullah has admitted to that shooting and faces four years in prison under the plea agreement.
Wyatt claimed he drew his weapon and shot after Abdullah threatened him and showed his own gun.
The defense asked jurors to find Wyatt guilty of self-defense in Abdullah's shooting, and passion provocation manslaughter for the killing of Micah.
The state said evidence showed that was not possible. It was one of the four shots Wyatt fired as he walked up the bleachers toward Abdullah that struck young Micah in the neck.
A total of eight rounds were fired, according to the evidence.
The child was already hit when video from a freelancer shooting highlights for ABC in Philadelphia captured the last four, showing Wyatt continued to fire at Abdullah after the man was already down.
Abdullah was paralyzed. He testified from a wheelchair that he didn't know who shot him, even though police body camera footage captured him telling those trying to save his life that it was Alvin Wyatt.
Nearby was Micah, shot in the neck. He would die days later without regaining consciousness.
Cody Griggs, then 15, ran with his friends when he heard the gunshots. He felt the bullet strike his arm, but testified that he didn't feel the sting until they made back to the car.
Micah's and Cody's mothers sat together quietly in the courtroom Thursday, holding hands as the verdict was read.
Angela Tennant and Keisha Brown never met before the trial.
It was luck that separated their sons that night, Chief Assistant Prosecutor Seth Levy told the jury during opening statements.
It was the bond of motherhood that connected the two women now.
After the jurors rendered their verdict, Superior Court Judge Donna Taylor found Wyatt guilty of an additional charge of possession of a weapon by a certain person.
Wyatt has a criminal history that bars him from legally possessing a firearm.
His sentencing is set for Sept. 11, when he faces life in prison.
