Keeper Trade Question

Have been approached about trading Zach Ertz in a 4 player keeper league. Other owner was willing to work a deal with him sending me Fournette and Jordan Reed. Sitting at 2-3 (7 of 10 teams in league are 3-2 or 2-3, 4 make playoffs), I like how my roster is set with adding Yeldon last week. Here is roster

QB Wilson Bortles
RB D Freeman Howard Yeldon K Johnson Breida Miller
WR Julio Diggs Baldwin Davis D Jackson
TE Ertz

Given how bad the tight end position as a whole is, should I even consider it?
