I sort of agree.
Henry era:
2002 - gets a pass as he took over during the offseason
2003 - great team
2004 - great team
2005 - team was obviously taking a step back with the starting pitchers being Arroyo, Wakefield, Miller, Wells and Clement, still competitive but WOOOF, also Rentawreck
2006 - results weren't as good as 2005, but the team was in a much better position after adding Beckett and Lowell
2007 - great team
2008 - great team
2009 - good team that overachieved while inserting young players
2010 - good team, but OF became a mess after the Ellsbury injury and Pedroia only played 75 games, can't complain about 89 wins but it really felt like a lost season at the time
2011 - good team that died at the end and became a mess of clubhouse drama
2012 - ugh, by adding BV and going with the same clubhouse as the prior year, they were courting disaster and it came
2013 - great team that saw FA players having career years
2014 - offseason acquisition was AJ Pierzynski, basically counted on having to duplicate the 2013 seasons from aging players and hoping younger guys stepped up, did not work at all
2015 - replaced Lester and Lackey with Porcello and Miley (5 ACES LOL), added Pablo and Hanley, also did not work but younger positional players were maturing and there was hope for the future
2016 - good team, added Price to calm down the rotation, traded for Kimbrel, Mookie became MVP caliber
2017 - good team, Sale was an ok pickup I guess
I think the only years I really have a bone to pick with were 2005, 2012 and 2014.
It makes sense that there would be a let down no matter what in 2005, but that rotation was really bad.
They should have made more of an effort in 2012 to remove some of the clubhouse stink and BV shouldn't have been allowed through the door.
2014 was similar to 2005, but it really felt like just throwing s*** at the wall and hoping every young player worked out. That was the year Xander was moved to 3b, brought in Rusney, and Middlebrooks was given his last chance. The opening day roster included Pierzynski, Nava, Grady Sizemore, Mike Carp and Jake Peavy. There's no way that would work long term.
