I feel somewhat the same about Duke as you do. But they do return alot. They essentially only lose their starting midfield. They do have Jones and Class returning, and have a top recruit Bruckner coming in, and they could always shift an extra attackman out there if they need more punch. Probably deserve the #1 ranking going into next year, but the Terps did beat them 16-7 last year, so I am not handing them anything.
Virginia has some very good players, but they certainly don't appear to have any of those great offensive players that they have been known for in the past. Cockerton had a very nice year as a finisher last year, but they really need some other guys to rise up and fill out the rest of the attack: J.Pannell, Lukacovic, Van Arsdale, French?? Zed Williams is certainly a big talent, but the jump from Buffalo high school to the ACC is a big one, so he might need a year to get up to speed. LaPiere being back should get UVa back in the NCAAs but I would start them off around #10.
