I actually have been using a modified version of this strategy for years. I play in PPR leagues and have noticed the drop in TE production. So I try and land the top TE in the 3-5th round. Given an additional flex position I would love to be at the turn and be able to grab Witten and Gates. Every year these TEs will be in the top 70 highest scoring players, including QBs. Good idea, but like all draft strategies it requires you don't swing and miss on your later WR/RB/QB picks.
I think, therefore I am. I think fantasy, therefore I am unreal?
