1) Taylor would probably benefit from a year in AAA. Souza would not. He's either major-league material or not at this point.
2) Earlier this season, I was envisioning an outfield two years from now of Souza/Taylor/Harper. Now I could see Span being a real asset in the outfield for a few years.
3) Werth is the weakest link in the outfield going forward. Not because he isn't still a hell of a player, but because he is showing signs of wear and tear. I can't imagine the Nats brain trust counts on him for 130 games next year.
4) I'm torn about LaRoche. If you let him go because you think Zimmerman will take over, what is your contingency for when Zimmerman goes down? At this point, he is the poster child for "injury-prone". (I wonder if Souza could handle first as a backup to Zimmerman.) LaRoche has played a critical part in this team's drive to the division championship, just as he did in 2012. But he has back problems, will be 35 next season (though he may be one of those guys who keeps the batting skills well into his 30s), and he did have that 2013 season.
5) If Detwiler goes elsewhere, some team could get a real find in him.
6) I wouldn't be surprised to see Blevins have a good 2015 season. Relievers.
7) It was interesting watching Espinosa, who was given every chance to secure a starting job at 2nd this year, trot out with the scrubs last night while his former peers all took the night off. And interesting to see that Detwiler, who's been a National for about as long as anybody but Zimmerman, was the first scrub called on to pitch when the Triple-A guy finished his stint. (Detwiler looked he was sweating beer from all pores before that inning ended.)
