Trade offer for DJax what to do?

I have gotten a trade offer for DJax. Hes offering me John Ross for Djax

this is a full point PPR, 10 man league

Do you think i should go for it or get Gallup and John Ross for DJax?
my team:
QB:Big ben, lamar jackson
RBs: Lev Bell, Gurley, Chris Carson, David Montegomry, Singletary
WRs: Thielen, Robert Woods, Mike Williams, DJax, curits Samuel
TE: Mark Andrews, OJ Howard

His WR core is weak and he has AB so hes on the fence right now.

I like John Ross for DJax, but if you can get Gallup from him too that’s just icing on the cake. DJax is either two deep TDs and a ton of points or nothing. For consistency I like John Ross at least until AJ Green gets back. Plus you have good WR depth so you should be fine

I would need to drop someone then and I am not sure who to drop. Or I give mike williams or curtis samuel along with DJax for john ross and Allen Robinson/gallup?
