I'm assuming that JR is going to be fired in the very near future. While I think that too much is usually made of a manager's contribution to a team, I think the manager should be fired in this case because the team failed to show upward mobility.
To me, the more interesting question is what the team should to with NH. All of the recent talk about trading prospects for major league players has me concerned; I think it is too early to do that. As frustrating as it is to be patient at this point, you generally only should trade prospects to round out/suplement a competitive major league club. This club is clearly not there yet (perhaps a year from now we will be). Making such trades at this point would seem to un-do much of the appropriate vigilence and patience since FC & NH took over and began to build the franchise from the ground up. Instead, this team needs to be supplemented intelligently free agents even if it costs a lot of money (a pipe dream for several reasons, I know). Nobody - including me - wants to be patient, but trading a guy like Marte at this point for anything less than a very good, established player or a big league-ready prospect of equal pedigree would be a mistake.
I generally like the job NH has done and I wholeheartedly support the process they have been utilizing. But I'm worried that the pressure to win now could lead to a regrettable change of course (somewhat like what happened following the 1997 season). If I recall correctly, NH has but one year remaining on his contract. Might some of the pressure to win be eased (thus decreasing the liklihood of an illadvised and calamatous change of course) by extending NH now, even in the face of the festering, unpolished turd that was the almost completed 2010 season? If not, should NH be let go now to avoid the above scenario?
Just thinking aloud here.
