Actually most players don't improve significantly anymore. Some do of course. But generally you improve slightly or remain about the same. Depends on when you debuted and what your skillset is.
Anyway, Francoeur's best non-rookie braves season JMO was his first full season. His best season offensively was his rookie then 2011. I like Francoeur's 2006 more than 2007 because he was actually swinging at balls. In 2007 he because a punch and judy hitter unless someone hung a pitch. Only think I liked about 07 with him was his walk rate going up. His 2007 though was why his sucked so miserably in 2008. He had so much luck in 07 as a slap hitter that he assumed it would continue not realizing that his swing was way more tailored to a power hitter so when his BABIP failed he was left without his power. If he could have kept his power swing and slightly improved his pitch selection he could have been a better player. That said he managed to stick around the majors for 8 seasons so far and make nearly 26M so I guess I can't knock him too much.
BJ might really benefit from therapy.
I didn't see any difference.
BJ at his best was a great player. I will deal with him playing like he did in 10-12. Having a 3+ War in CF instead of the near -1 he gave us last year that's a huge improvement. Hopefully he'll be back to being 105-115 wRC+ with his defense. Defense last year was fine, his offense was the problem.
That said, still wish we had Bourn. Remember when you bet that BJ would be better over his contract than Bourn? Bourn is off to a hell of a head start.
Cant wait for next years "No way it happens 3 years in a row, not gonna happen" line.
