Until someone makes an idiot of me in a league I'm in, I will never jump at a TE like Gonzo or Shockey in the 3rd or 4th round. Let your competitors take them early and pick up stud WR's like Eric Moulds, Koren Robinson, Amani Toomer or Donald Driver.
Then, in Rounds 7-9, I would eye Marcus Pollard, Alge Crumpler or Billy Miller -- in that order. Until TE's start getting into the Top 20 in overall receiver fantasy elites, I'll stick with making RB/WR/QB's my priority. When they're taking TE's, pick up the fantasy studs. Personally, I believe that most fantasy seasons are won in Rounds 3-5. Don't blow those opportunities on players that are one TD away from either becoming or falling out of the "position elite" within the TE tier.
