So, just looking around the league a quick bit. Would a package of, say, Gordon (top 30 on most prospect lists) and Gonsalves/Romero (top 100 on most prospect lists) + 2 top 20 system prospects (Wade? Littel?) be enough for any of these guys?
These guys had good seasons on teams that should probably rebuild -
Mets Jacob DeGrom - 3 years left - 30 years old next year. NL pitcher who has topped 200 just once (this year). 5 WAR pitcher last year.
Phillies Aaron Nola- 4 years left - 25 next year - NL pitcher - 168ip is max so far. 4 WAR pitcher last year. Some injury history.
Pirates Gerrit Cole - 2 years left - 27 next year - NL pitcher - 200ip twice - 3 WAR guy last year - ace of Pirates pitching staff and huge former prospect. Never quite lived up to prospect billing but good starter.
Giants Madison Bumgarner - 2 years left at 12/year - stud pitcher with great reputation. Probably not likely to be moved as is arguably face of franchise and WS hero.
Blue Jays Marcus Stroman - legit ace this year - 6 WAR pitching in AL East. 3 years control left. Only 27 next year. Topped 200 twice. Short pitcher same issues you heard about with Berrios. Not sure Toronto is going to go full rebuild. Out pitched his fip, if you care.
A's Sean Manaea - 5 years of control. Not as good as the rest of these guys. Plays in Oakland which helps pitchers incredibly. Lowish k-totals. Former top 100 prospect. A's always looking to trade guys.
Tampa Archer - I don't think Tampa would move him, they aren't that far away. If they did, he's probably #1 on most lists and Twins would probably have to up their offer.
These guys had bad seasons on teams that should probably rebuild but are still young enough and were highly regarded prospects or older but might still have something.
Phillies Vince Velasquez - lots of strike outs, lots of walks. 26 next year.
Kevin Gausman - uber prospect, three years of control left. Has all the stuff, never quite put it together for a full season.
Reds Robert Stephenson - former top pitching prospect. Tons of walks, control issues. Not sure if starter or bullpen. Their Buxton prospect for years. Only 25 with lots of control years left but hasn't really figured it out for a while. Probably a better Alex Meyer type at this point.
Seattle - King Felix - bad season for him. Injured. Owed tons of money over next two years. Seattle would probably move him but he can veto a trade. 32 next year.
