Mid 80s Bird was at his peak, in the midst of his mvp run, widely regarded as the greatest player on the planet. McHale was and is regarded as one of the 4 or 5 best low post scorers in NBA history.
These are the kind of players we're hoping JT & JB become. They're just not there yet. To say they are is essentially - in using today's players as a comparison - putting them on a plain with Jokic and Durant.
