The main risk with heat seeker tackling is that you are subject to the defensive fake out system that is triggered by ball carrier evasion moves. If you decide to steer in without using heat seeker (or turn the heat seeker option off) you are not subject to the fake out system with a user controlled defender. Also keep in mind that you will only feel heat seeker activate if your stick direction is off from the intersection point with the ball carrier. If your stick skills are on point, you should rarely even notice that heat seeker is there. Also, you can’t just hold the button down the entire play. It works similar to the tackle prep timer from previous years, you have the judge the distances appropriately because if you hold the tackle/hit stick down too early, your player will lunge early and miss the tackle.
