Burnes is basically like a free agent though- you get one year at his last year of arb rate and then need to extend him at a close to market rate.It sure it. But that's why I made my original point that I don't think they'll go for two in free agency. I've never loved free agency, because you're at the mercy of what happens to be on the market that year. Targeting a trade with prospect capital can potentially give them an option of someone who they feel has a high chance of success. But it will always be risky.
I think they need to trade for someone with more control. Burnes teammate, Freddy Peralta, would be ideal- 3 years / $22M left for his age 28-30 years. But, Milwaukee would ask for a haul.
