The thing Eaton had that really made him the player he was was a very good sense of timing and good reaction times. He could recover and block multiple shots, he followed the ball well and knew when to make the move for the block. Not easy for any big to duplicate. That would still translate into today's NBA and he would be a paint enforcer especially with a zone.
And he was ****ing 7'4".
Eaton would do just fine in today's NBA, good lord.
