Yes. If bucks can get as big as the ones listed below does can certainly reach 200, probably not many do but it's possible. I hunt a lot on the Eastern Shore and the deer over there are far bigger than the ones I hunt in other counties in VA. I killed a young buck during gun season that weighed 180lbs and another during bow season that went over 200. I have killed many does over there weighing 140-170(admittedly a guess on the does, I think I'll use the scales more this season to besure and satisfy my curiosity)but none breaking 200. I'm sure there are probably a couple roaming around there though.

The Whitetail Deer
.......For example, the largest whitetail on record was a Minnesota buck with a live weight estimated 511 pounds. On the other hand, adult bucks in the Florida Keys weigh as little as 50 pounds. In various regions of the United States, bucks average from 100 to 150 pounds. Deer over 300 pounds, are exceptional anywhere...........
Same buck as mentioned above just more info:

Heaviest whitetail
In November, 1926, Carl Lenander Jr. dropped a monstrous Minnesota buck with a single shot. The field-dressed deer weighed 402 pounds. Conservation Department officials estimated its live weight at 511 pounds. No heavier white-tailed deer has ever been recorded.
