This is a good tool for projections. I don't like their in-season analysis but they do pretty well with rankings.http://www.fftoolbox.com/football/2009/ ... yer_pos=TE
In standard leagues you would see better projected point production from:
29 running backs
12 wide receivers
That's 69 players total with higher projections than Jason Witten (the highest ranked TE). So yeah, if you want a top flight TE you're going to have to pony up a 4th or 5th round pick. It all comes down to position scarcity. If you feel like you need a TE then draft one. I prefer to stream my TE against defenses with weak pass rushing and a weak linebacking corps. It's also going to come down to your draft. If the top tight ends go early I'd say screw it. If Witten or Gates is out there in the fifth round then make your move. I still think my first four picks would be 2 RB and 2 QB. And I'd always flex a RB instead of a WR.
Plug your numbers in and see what you come up with.
