Heck, we don't even have all the tape in. The 12-team playoff is going to be huge for a lot of prospects. And yeah, there are a lot of prospects or positions where I don't really want to judge guys until we have Combine results in. DEs and RBs especially.
For example, the book on Tre'Veyon Henderson is that he's not much of a blocker or receiver, you're drafting him because of his explosiveness as a pure runner. How talented of a runner is he? Well 40 times and jumps would go a long ways towards qualifying that. If he goes full alien mode and runs like 4.4 flat with a 40" vert, he could go second round. If he disappoints and runs a high 4.5 or 4.60, he might fall into Day 3. Same tape, but measurables at that position matter so much.
