Apologies if I've said this before, but what I've read about Funchess is that you can separate out what is a typical WR1 route from a typical Slot route. On his Jordy Nelson routes, where Carolina wanted to use him after drafting him so high, his completion percentage and catch radius was terrible not helped by his lack of speed. But on his Slot routes he fared much better, with a really good radius and completion percentage. It's likely Indianapolis figured this out and was going to use him differently, but then he got hurt. I don't know how good he is at blocking (though for WRs I see that as more a matter of effort than skill), but I envision GB using him more as a Slot or Heavy Slot kinda possession guy who is up the middle a lot to play against Strong Safeties and generally getting the 7-yard passes.
