Let's say a top pitching prospect nets you 10 WAR in his first six years.Gibson, who is, well, up and down and more like a #4 type pitcher than a #3 type pitcher, already has 5.8 WAR with only 3 years of service time). Not really that great, but as we know a huge chunk of top prospects end up just meh, right? That's just how it goes. In the next 6 years, one WAR will likely average out to around 9M. So just a weak #3-decent #4 pitcher, averaging 1.66 WAR a season during his controllable years, will be worth about 90M. He likely doesn't get even a total of 2M in his first three controllable seasons. Then, if he's only producing about 1.66 WAR a season, he likely doesn't get over 20M combined over his next three years. Maybe he does. Let's be generous and say 25M for his arbitration years and 2M for his pre-arbitration years. That's 27M paid out to a player over 6 years who was worth 90M in those 6 years. 63M worth of surplus, for just a #weak#3/decent #4 type pitcher. Fangraphs (which thinks less of De Leon than a guy like Sickels) sees De Leon as a solid #3/#4 type pitcher. By comparison, an Ace type young pitcher like Noah Syndergaard, has already accumulated 9.6 WAR after two seasons which have been worth about 76M while he's gotten paid about 1M. 75M in surplus value (after ONLY two seasons. Imagine what the surplus value will be like for him after 6 years of controlled time). Looking at Dozier. If he averages about 4 WAR over the next two seasons, and one WAR during the next two years averages out to about 8.5M per WAR, that's 68M value. His salary is 15M. That's 53M in surplus value. So yeah, I still think Dozier is worth more than JUST De Leon, but not that much more. It's not a slap in the face offer. Some seem to think two years of Dozier is worth closer to a Syndergaard pitcher than a De Leon. And before we say, well, De Leon could end up being a bust, that's simply the case with any pitcher. They're just harder to project which is why clubs like the Cubs like to build their core around position players. Then they either trade players/prospects for proven MLB pitchers or just outright buy high quality MLB pitchers on the market for the rotation. We choose not to do the former and apparently can't do the latter. That leaves us with waiting on the draft/development or trading chips like Dozier for quality prospects, hopefully close to MLB ready) to help fill our rotation.
