Roy probably isn't that bad of a choice at the moment since, as others have pointed out, no one else has really put themselves forward. That being said, pining him as the next in line before the start of the county championship, when a lot of players are going to have a good many oppertunities to score runs and put their names forward, would be stupid. I don't mind going to Roy if no one puts their name forward, but the likelihood is that someone will.
Hopefully Duckett gets runs at the start of the season. I think the two test marches he had opening in Bangladesh were pretty tough with him even scoring a 50 in the second test which iirc was particularly low scoring. He was exposed against Ashwin in India but you'd have thought his game has improved against spin, and he's skills against pace bowling would become more relevant in England
