When you look at the forwards available in free agency this season, there’s.....not a lot out there. Alexander Radulov is by far the most dynamic offensive target out on the market - and there’s not guarantee he leaves Montreal, either. He’d also be incredibly expensive and probably command a lot of term on his deal, so I’m not sure how much of a fit Radulov would be in Dallas (though they have the cap space if the winger is tempted to bring his talents to Big D.)
No free agent signing this summer will blow your socks off outside of Radulov, most likely.
