It's a slippery slope to play the "what-if" game about taking out an important component of one of the most important pieces of machinery that gave us our playoff success.
And it's a targeted subjective take to say that Brown's $3m is what's costing us this offseason. You could blame Holland's inaction to extend them during the season, his lack of foresight to trade Broberg after Broberg made it known he didn't want tk be here, the Nurse overpayment, the Kane term, you could go as far back to the Lucic situation if you want to point out Neal's $2m that is still on the books.
There's obviously more than just one move that results in this sort of financial situation.
