Syndergaard managed to get $13M coming off a bad season. Any random free agent 4th starter gets 1-$10M. Maeda should easily beat that. I see 2 years $30M as his low end and a bidding war would push it up to 3 years $40M. If you attach a draft pick to him with a QO that probably hurts so maybe his bottom end is 2-$28 and top end is 3-$36M.
If I'm Maeda I take 1-$20.5 instead of 2-$28 but not instead of 3-$36.
