nice looking player so far. more ppl need to build good blocking TEs and are It think.
anyways, you need stamina. I'd train it hard in the off season. Your blocking is fine for a long time too. Seems weird, but blocking is overrated for a blocking TE, since you are rarely pass blocking. Raw power and pancaking that speed DE or LB is the goal and strength is where it's at. Tons of agility, some more speed, and enough stamina so that you aren't gasping for breath after being in there two straight plays and your guy will be alot better. He could even have a near 500 pancake season like my level 34
