Evans' numbers are about average, some slightly above, some slightly below, for a TE, although he did place 1st in the 10 yard split drill.
Given his size, at 6' 5", 258 lbs, though, those numbers actually end up being better.
Cross' numbers are around the lower end of being average, but in his case, because he's a smaller interior DL, that works against him. He's going to do the rest of the drills at ND Pro Day, after getting a bit more time to heal up (he wasn't anywhere near 100% during the playoffs, and even now at the Combine).
He's definitely going to be slated to play either 3 technique tackle (DT) or strong side DE in the pros. The days of a 285 lb nose tackle in the pros are long gone (been that way since the early 90's).
