James Vince. Looked a class act whenever I've seen him bat, probably not as talented as Sam Northeast or James Taylor, but he's clearly got alot of natural ability. I'd back him to make an appearance for England at some point. Ben Stokes looks a handy all-rounder as well. Be interesting to see how he goes for Durham next season, if he gets a few games anyway.
Edit: Forgot about David Payne too. Nice to see a quick bowler coming through the ranks, our fast bowling stocks are incredibly slim. If we were to lose a 2 of Anderson, Broad and Onions to injury we'd be screwed, especially in ODi's. Hopefully Shazhad, Woakes, Meaker, Finn and Payne'll develop well.
