Doughty is awsome, he is going to be top 5 D in league very soon for a long time but he is getting overrated in this thread. Last year was not the best for him and Stamkos had two amazing years in a row.
This could be offered to Lombardi and it would take him at least two weeks to decide if he should do it our not. By then Stamkos is either signed or offer sheeted, then matched. As a neutral party, I'd rather have Stamkos, LA needs to add.
