..it's all so clear what should have been done. But in an attempt to demonstrate how it's not always so clear at the time, let's consider two different players:
Player A: Player B
Games 266 / 321
PA 953 / 1135
HR 42 / 43
BA .248 / .264
OBP .300 / .326
SLG .455 / .442
OPS .755 / .769
OPS+ 94 / 101
AB/HR 21.0 / 23.8
SO% 34.2% / 21.0%
BB% 7.3% / 9.1%
Both players play the same position, with Player A being a plus defender and Player B an average defender. Both are below average baserunners. Player A is 25 and player B is 27, both in their 4th year in the majors.
With similar makeups, Player B looks to be a slightly better hitter, with less strikeouts, slightly more walks and a notably but not significant better OBP. Player A's younger age and better defensive skills probably offset the minor offensive deficiency.
So, you're the GM.....you need to trade one to fill another need...and keep the other. Which do you trade?
The Davis numbers are his Rangers numbers and the Moreland numbers are through last night. Interesting to me how close they are offensively and yet most around here (including myself) are ready to see just about anyone other than Moreland fill the first baseman's role.
Admittedly, Davis' pedigree and youth made him more attractive at the time of his trade than Moreland is today...but still....they're resumes don't look too different.
