If you're talking casual play, off and on for a year, then yes it's highly unlikely. If you're taking about spending a good part of a year, reading some of the best books out there (I recommend Harrington on Cash Games Vol. I and II) and then methodically applying the techniques in those books to your play, it's doable. Or at least, when I took some time off between startups, I was able to average being a reasonably profitable poker player at cash games in casinos.
However, I came to the conclusion that it was a good learning experience and that $80k a year was not worth having to sit in a room with a bunch of guys, hunched over a table, breathing in their germs, and listening to their half drunk rants. Great lessons to be learned from poker though, but you must be dedicated to average being profitable. If I go back and try now, I'm probably going to lose more often than not.
