JacobyEllsbury is about 40 million under the cap, and flynnatic is already done and has 20 million left, maybe contact one of them for a trade to get you under.
Worst case scenario is we choose somebody to kick off your team (it won't be one of your top 3 or 4 guys, but probably a pretty good player making a lot of money)
Another option is to pick Julio Lugo and make him your starting point guard, that would be fair
