I'm not quite sure I understand the dislike for Devin Funchess. He's a play-maker, a gifted athlete, has a huge frame, catches the ball well, has great short-area quickness, has some long speed as well.
Is this about blocking concerns? I'm not sure how concerning that really ought to be. For two reasons, really.
First off, players can learn to block. It happens all the time, if they have the physical ability. Even Michael Egnew was a decent blocker by the end, and his exit from the league had nothing to do with his blocking ability and everything to do with him being too dumb to execute a playbook and be a functional part of a sophisticated passing game.
Secondly, I don't think guys like Jimmy Graham and Jordan Cameron are great tight ends in this league because they block, nor were teams especially concerned with their blocking weaknesses as glorified wide receivers when they came out of school.
So just keep in mind, the most important thing to evaluate are his matchup skills in the passing game.
I mean, get an NFL caliber safety like Kurtis Drummond matched on him and he kind of makes this look easy:

Putting corners like V'Angelo Bentley, Doran Grant, Trae Waynes, Bradley Roby, Cody Riggs or Jordan Ford on him might fit the legal definition of abuse:

Not gonna be easy for linebackers like Glenn Carson, Kolin Hill or John Law to keep up with the guy, man or zone:

And best of luck to you if you try and get cute and have a smallish end like Romeo Okwara pull out to try and deal with Funchess:

This is what it's all about. It's where the rubber meets the road. You have a tight end on the field because he's a matchup nightmare. You get a safety on him and he's too big. You get a corner on him and he's way too big. You get a linebacker on him and he's too fast. You get a defensive lineman pulling out in zone and he's way too fast. Matchup problem.
I'm not saying he's perfect or anything but he's a pretty good prospect for the position.
