Seems what is being ignored here is that we'll have more cap space next year. Wallace's salary will be off the books with the trade, and we don't have Green's player option hanging over our heads either.
Not saying I would do it, but I think the whole "overpriced Gay" angle I've seen in a few post misses the point completely.
The question is, will having Gay now thus making us the favorites to retain him or the alternative if deciding not to keep him and having more cap space next year is more attractive than staying the course with Green and Wallace, one who has a player option and another set to make 10 millions next year as well (and in the meantime look for other opportunities). And of course the retention of the 1st round pick.
