Tricky Kelce TE situation

Current roster (12 man, .5pt ppr):
QB: Cousin, Rivers
RB: Murray, Martin, Powell, Henry, Cohen, Woodhead
WR: Evans, Crabtree, Adams, Rish Matthews
TE: Kelce, Olsen
D: Steelers
K: Nugent

Kelce is out for the week.

Should I hit the waivers and stream a tight end and who would I drop?

Or should I try and package up a trade with Olsen and pick someone up, in a must win situation.

I’d drops Cohen for a tight end unless you get a deal to get a wr as there’s no one this week with Evans out and crab on bye adams hundley-ing and matthews whos not been great this year

What kind of WR do you think I could get for a Olsen/Cohen package?
