Ronald Acuña Jr.
There is no question that Ronald Acuña Jr. is in the conversation of the best player in baseball right now. However, if he continues at this pace, even if he slows down in his later years, he will be in the conversation for the greatest player of all time.
In just six short seasons, Acuña already has the following accomplishments: National League Rookie of the Year, National League MVP, 4X All-Star, and 3X Silver Slugger. He is also on pace to hit over 400 career home runs in a 15-year span from the leadoff spot which is absurd to think about.
A career WAR of 26.7 is a great place to start and he owns a career average of .292 with 161 HR, 402 RBI, 143 wRC+, and .388 wOBA.
He will continue to be a speed threat in his younger days as long as he stays healthy. However, it is hard to say what he is on pace for because inevitably time and age will take over and slow even the best base stealer down.
Ronald has 180 stolen bases over 6 years which averages to 30 stolen bases a season. If he keeps that pace he will have 450 stolen bases considering that 15-year mark. That would give him the 55th most stolen bases in baseball history.
If there is one knock against Acuña, it's that he isn't the best defensive outfielder. He has a great arm and makes some great throws but he doesn't have the best range. Acuña's OAA sits at -12 for the position of right field.
