In order to clear enough space to sign a max guy, they almost assuredly would end any LT streak thus resetting the progression, wouldn't it? Like, if they sign Fournier, enter into LT territory, then let him walk after this season, stretch Horford's $14 Million for 7 years, and then sign Bradley Beal, they would be nowhere near that tax threshold until it was time to extend those of their current rookie deals, from what I can see.
So to me, it's inexcusable not to sign Fournier to a 1 or 2 year overpay. If Beal becomes available ship Fournier anywhere for a second-rounder just to clear the space. Heck, send Horford out with a 1st rounder if it means clearing the space and not having him linger on the books, for Beal.
