Possibly there just a few holes in that theory I will be happy to point out
 * In the 2nd episode, "Jay" was shown to have no remnant of the Speed Force in his system while Zoom is maximum speed force.
 * "Jay" was dying from Velocity cancer.
 * If "Jay" WAS Zoom, he would know where to look for Wells instead of rampaging through the city setting buildings on fire.
