Effective long reliever that pitches multiple innings multiple times a week
all do not exist.
Short relief is max effort in short burst. With a few outliers you will find they pitch up to 70 to 80 innings but 60 innings year in and year out seems like a better limit
Long relief would be someone that needs a starters repertoire or a reliever that can minimize pitches thrown. The latter case would likely be good enough to be in the back end of the bullpen. That leaves someone who could be starting but maybe should only be going through a lineup once. That is usually called your fifth starter.
Mark Guthrie pitched 75 innings in 1992. That is not really much difference than a short reliever pitches. He made 58 appearance so it was not like he was a long reliever very often
The article above here on Twins Daily you might have read mentioned Left field, right field, and first base as the areas of concern. 2-3 war is considered strong play as defined by fangraphs in their glossary. If you look at the blog again you will notice that 2 of the positions are reported to project 2-3 war. That would suggest by definition of war that there is adequate play out of those positions.
Fangraphs describes a 2 WAR player as a solid player. If there is only one position that has a less than solid player then the Twins are not doing too bad.
Perhaps one needs to remember all the spring training mashers who did not pan out. Lament the trade once CES has 3-4 hundred AB at the major league level
If you are going to blow up the top of your minor league for one player there has to be an extension. If you think that anything less than 2 of the top 3 prospects plus a near major league ready starter is going to get the deal done, go do research into trades of similar players. If you think he is going to sign for Robbie Ray money, ask yourself is Burnes and Ray equall. Don’t be comparing contracts unless you are looking at similar pitchers.
There is season after season of data that would suggest Buxton will get hurt regardless of management styles. They might as well play him until he breaks
Likely 2 out of the three if you look at when Sale and Grienke were traded. It would still take another prospect. Just maybe what is missing in the proposals is a star outfielder like Kepler
You forgot the deGrom contract. That is the contract that is closest to a player of Burnes talent. Also look at the contracts signed by top players historically to avoid arbitration and you will find some upper 20 million contracts for the last year.
