As the title states, why it is so hard to build with free agents. This is a look back on what happened after the contracts were signed. What kind of return did the team get for the money. Building blocks are those players that produce more than 2 war. Fangraphs defines a 2 war player as a solid player. They define a 3 war player as a good player. for numbers above that they have superlative kinds of words. For looking up WAR I used baseball reference as it was much easier. I excluded relief pitchers from consideration for several reasons. 1. I am not sure that WAR measures what they do well enough to compare them to position players. Over a 4 year period very few seem to break a cumulative 8 WAR. 2 is obtainable. That is a great reliever, not a solid one. It just did not seem comparable. I used the ESPN tracker for years and dollars. For the contracts that have not been completed I used what Bref said they were paid. AAV might have been better as Pujols and Sherzer's contracts are pretty back loaded. I did not give any discounts for injury plagued years. The player was still paid. If the player was released, the years and money counted. If the player retired, the years and money did not count. The Grieinke rule. If you opted out at three years, it was a 3 year contract. FWIW, that was the only great 3 year contract. I wished I had a computer spreadsheet that I knew how to blow numbers into and do calculations on the data. Life would have been easier. The data I present will be from players who signed contracts 4 years or longer. I started looking at 2 year and 3 year contracts, but the numbers were looking horrid. Upon further consideration, I decided 2 and three year contracts are more bridging than building. From the free agent class of 2006 to 2014 66 players signed long term deals. 6 of them averaged 5 WAR or more for the 4 years prior to free agency 12 4-5 WAR 25 the 3-4 WAR, 15 2-3 WAR. There were 7 7 that did not average 2 WAR the previous 4 years. Nick Markasis was one of these. In years 2-5 he was a 4 WAR player. Ervin Santana was another. He has 5 solid years on his resume to go with the 5 bad ones. Adam Dunn, Gil Meche, Jeff Suppan, Omar Infante and Brandon McCarthy were the other 5. Of the 6 5+ War players Beltre and Cano were the only ones to maintain that. Pujols, A Rod, Teixara faded from greatness, Matt Holiday faded to very good status. Of the 12 4 WAR Cliff Lee maintained, Max Scherzer became magnificent, Buerle, and Sabathia were in the high 2. The other 6 averaged well below 2 but none have finished as a negative. 66 free agents. 20 have bwar that average 2 or more for this time period. As a group they earned 1.833 billion dollars., played 116 seasons of baseball and averaged earning 15.8 million a year. They accumulated 337.6 bwar. They averaged 2.91 WAR. Their cost ber bwar comes out to 5.4 million. Still should be less than 6 if one used AAV for Scherzer and Pujols. I am not sure were back loaded enough to make a difference. 66 free agents. 46 of them were not so good. They played 209 seasons. They accumulated 145.3 bwar. That averages out to .7 bwar per year. They earned 3.827 billion dollars. That works out to 18.3 million a year, or 26.33 million per war. Given that this is over 9 years the takeaway is that more than twice as many free agents fell below being a solid player than not. The players with a high bwar were not immune. to falling into mediocrity, 7 out of 18 below 2 war, half ended up below 2.5 for the contract. Of the 48 players who averaged below 4 WAR only 6 maintained an average over 2 bwar. That is why it is hard to build with free agents.
