I certainly don't try to run TE streaks very often, and my TE's are most used with the stick play as the primary option (if my outside receivers aren't one on one in press). Still, the TE post play can be very effective, and on the sliders I play on, a bulkier guy is much more likely to elude tackles than a smaller, shiftier wide receiver. I also like to run the PA power O plays which often can hit the TE 15-20 yards downfield and potential YAC if there is enough room by the sideline. A TE running a streak route is also the best hot read on the field to hit ten yards out before a safety has had a chance to cover.
I tend to average 6-8 catches for 80 yards or so with my starting TE, while my top slot receiver might get 4-5 for 80-100 and my top outside receiver (s) might go 3-130 or so. The other guys are the ones who can beat the coverage, but the right play can still get you really good yards with a TE.
I've found that more often than not in a closely contested game against a top opponent, when the deep routes are shut down by great safety play and/or pass rush, my TE is the one to make a big play with YAC.
