A lot of it has to do with gameplanning. Comb through your playbook and see what kind of pass plays you have selected. Target plays that either have TE or SE in the name of the play — which indicates the TE is the #1 read.
I recently took over a team that had a 99/99 TE on the roster, so I selected at least 5-6 pass plays that were specific to him. After 6 seasons, his previous career highs for any given season were 46/542/2. My first season with my playbook, he went 56/809/8. With a couple more adjustments this off-season, I hope he will break 60/1,000/10 next season.
It takes some thought and work, but once you have a good gameplan set, it makes a world of difference.
