Just five days ago, Nik Stauskas was contemplating walking away from professional basketball. The 29-year-old journeyman had been out of the NBA for nearly three years – aside from a 10-day stint with the Miami Heat at the beginning of January – and he felt he had given everything he could to the game he loves. However, that thought went out the door as soon as the Boston Celtics came calling toward the end of last week, as Celtics President of Basketball Operations Brad Stevens plucked Stauskas away from the G League and inked the guard to a multiyear deal.
