Should I look for a new tight end?

Yes. Fleener, Ebron or Hooper would be good choices

I have Eifert on my bench,behind Fleener..

Eifert has elite TE talent when healthy,& when Dalton is playing good.

Eifert caught a TD pass in week 2,but the refs took it away.

I am not giving up on Eifert;I'd rather have him as a back up TE,than a back up QB on my bench.

I suggest you pick up a TE of your choice (I prefer Fleener),but keep Eifert.

Fleener is the pass catching TE Brees likes,,and Brees can make a TE look REALLY GOOD;If you remember how good Jimmy Graham was as a Saint.

(Remember that A.Gates is P.Rivers favorite redzone target.)

Eifert is still a TE1 each week. I think that Dalton and the offense will come around at some point, but if you want to have a backup plan or someone to stream then I would grab Henry for sure. Ebron showed signs last night that he could potentially be the player we thought he would be when drafted, but Henry is proven and LAC throw the ball all over the field with Rivers.
