You can say that with him coming off a career year, and as I pointed out the same was true of Aubrey Huff 2 years ago, and isn't true anymore.
After 3 of the past 5 years, I would say that LaRoche wouldn't have been projected to have any value at all in 2015.
In any case, this is not a controversial statement to make: ML 1st basemen who are 1/9 in career years above 2.5 WAR shouldn't count on much of a bidding war if they're 35-year old free agents.
Hasn't LaRoche been a pretty steady .250/25/90 hitter over his careere or so minus a injury plagued 2011 season? I really wouldn't make a big deal about his so called "career year" considering by the numbers, it's not that much better than his career norms. How does the park he plays in and the players he plays with come into play also.
