I agree with those who say that Werenski is an elite offensive talent. He is smooth, confident, and his vision is something special. He also has a great personality, and obvious leadership qualities. He reminds me of Brian Leetch in every aspect of his game.
I also agree with those who say that Provorov is a cornerstone D. It's hard to measure what he brings to the team. His focus and work ethic changed the locker room. Our young players, including Ghost and Nolan Patrick, undeniably look up to him. All he needs to do is stay healthy, and marry a good local girl so he stays in Philly forever. Who you pick depends solely on your team's needs. There is no "gap" between Zach and Ivan. They are simply different.
