There's no fixing it. It's a well known problem this year, has nothing to do with sliders . There's no slider set that can fix that. Only advice is to control a linebacker and shadow the TE, follow him everywhere on a pass play. Or you need to make coverage adjustments by spotlighting the TE or use the coverage adjustments where you can set the defense coverage to either underneath, over the top, inside, outside. And you can also set the player covering the TE to shade the TE inside or outside. I don't think TEs are "always" open but for the most part they're open on post routes unless you make the proper adjustments before the ball snaps.
