You have to grab Hall.
What's the difference this year?
So, I think Sharp has the tighter window. You'll notice the windows overlap significantly. Maybe you don't agree with these windows. Consider this carefully. What does it mean? Worst case scenario is you sacrifice a point a week (Hall's low versus Sharp's high). Best case is you actually gain 10 points.
Sharp is clearly in his prime. No reason not to hope for a few more solid seasons from him. Chicago needs him to be productive and will give him opportunity. He also has the potential to gradually move from shooter to playmaker. Some guys move effectively from one role to the other during the course of their careers.
Hall. Yes, he poses more injury risk. He also poses more Hall of Fame potential. He's taken his time, moving up the ladder in the NHL. Consider if he was a rookie this year, like Tarasenko. We'd all be extolling his vast virtues. They're only a month apart in age. So, Hall can clearly find some more, and higher windows.
This is a risk you need to take. Grab Hall while opportunity knocks. Sharp is great. Hall is currently very good, with a chance to be very great. Good chance he steps up to great this year! (he had about 50 point in about 60 games last year, so it was better than it feels)
