Since 2007, we've drafted Subban, McDonagh, Pacioretty, Price, Sergachyov, Galchenyuk. While not all are franchise players, they are in line to be, or are still top line players.
In that span, we have only gotten Radulov off free agency, for one year and Mike Cammalleri. So, I think even in that equation, it shows that drafting and development is simply the better option. Not to mention, ELCs in a cap world are a huge advantage over paying someone like Backes and Ladd 6-7 million at the end of their careers.
