Power Through is the break tackle SA that fires the most. Two pieces of AEQ in Power through may be worth it... it will trigger for any ball carrier when being tackled, regardless of if you are a TE, a WR, or a FB, or HB.
Power Through fires based off of weight and STR, if you have a Strong TE with decent weight you should be able to get it to fire a couple times to help you break open fomr the LB after the catch.
Lower The Shoulder and Stiff Arm would be a waste on a TE as they rarely ever fire (successfully) compared to power through.
How much STR do you have, how much does your TE weigh? What about Carrying how much Carrying to you have?
