Think the size issue is so sklly with tight ends. Vernon davis is only slightly bigger than hoskins, for example. The guy can make plays and its no fluke he was so productive in college. Reminds me of Goddard, one of the best at his position in college ever, IMO, but he never got a real chance before he left us way too early.
The unfortunate thing is, Cato, will suffer from this old school thought process as well over his size and will be lucky to get drafted at all, even as a heisman finalist IMO.
