The Pirates knew they were going nowhere even if they did sneak into a wild card spot, which they were a long shot to do. They didn't have the depth to make any kind of run.
The 2014 Giants are a terrible comparison. The Giants controlled a playoff spot the whole second half of the season, the only question was whether it would be wild card or division. They coasted the final month, especially the final two weeks after the Dodgers swept them, and willingly yielded wild card home-field advantage so they could line up Bumgarner pitch that game. They were an 88-win team but could have gotten to 92 easily if it mattered. They also had a proven championship lineup and bullpen.
The Pirates holding on to the playoffs would be like a 4-7 team keeping the journeyman QB in instead of the rookie. You might pull off a miracle and get one playoff game, but who the fork cares?
Two games out with two months to go is a long shot? Even if they add help instead of selling at the deadline? There is no way you believe that.
Also, I didn't say they were comparable to the Giants. Once again, you are responding without bothering to understand the post. I brought that team up in response to Fart's claim that a Wild Card spot isn't worth pursuing and that wild card teams are losers. Clearly, the Giants put lie to that claim. I never meant it as a direct comparison to of the two teams.
To your last point, no, that isn't true. Fist of all, Melancon is no journeyman. Secondly, the Pirates didn't have a losing record at the deadline. By your thinking, we shouldn't bother with the playoffs. Just assume the Cubs will win it all and be done with it. No way an underdog could sneak in and make a run.
By the way, one major reason the Cubs are so dominant is that they did add veterans to support their young core. Now the Pirates can't spend on that level, but they could have brought in help. At some point, you have to try to take that next step, but that takes a financial commitment that the Pirates' ownership will not give.
It's funny how the Pirates earning wild card playoff spots was such a huge deal to the baseball apologists when it suited your arguments. Now that their shot at making the playoff again works against you, the story suddenly changes. What a complete load of bullshirt.
