Large Trade In A Small League Question

Been going back and forth with this guy today and this is the first one he’s offered that I am kind of interested in.

He’s offering Evans, Cook, and Hunter Henry for Kelce, Woods, and Eckler.

I like moving Eckler for Cook and Woods for Evans, but it’s only an 8 team league so I’m really worried about loosing my TE edge by sending off Kelce. Standard scoring and below is my current team. Let me know what you guys think.

QB - Newton and Winston(dropping with Waivers for Lamar Jackson)
RB - Conner, Eckler, Kerryon, Damien Williams, Myles Sanders, Justin Jackson
WR - Adams, Lockett, Woods, Gordon, and A.J. Green
