All the things said about Albies being younger at a higher level are of course accurate and relevant. But, I'm looking at projection. When I look at Albies I see a pretty good bet that he will continue to develop into a good OBP guy with speed who will play good to very good 2B defense and will steal you some bases. Looking at Demeritte, I see a guy who is 2 years older but missed 80 games of one of those years for a PED suspension (which has to be taken into account as well) who has good to very good 2B power both in doubles and homers, with a reasonably good OBP, reportedly 70 defense and who will at least steal a few bases (not nearly as many as Albies). Right now, I still have Albies rated as the better overall eventual ML 2B BUT I am beginning to believe in Demeritte.
Some of that is my belief that positional tradition IS important to a ML club when constructing a line up, so I'm partial to 2B who can provide a higher level of productive offense as opposed to table-setting offense. When I look at the Braves ML team and try to mentally construct future offenses, I already see 2 guys in Inciarte and Swanson who are more of the table setting type of bats. Adding another in Albies will just make it more imperative that the Braves find production at other positions. I'm not saying it can't work. It can. But, it narrows the margin where if you get a .600 OPS out of third base and/or catcher then you are in trouble.
So, I'm thinking a future line-up of Inciarte, Swanson, Acuna, Freeman, Riley, LH hitting OF, Demeritte, catcher might be more valuable to the Braves (considering likely roster construction) as opposed to Inciarte, Albies, Acuna, Freeman, Riley, LH Hitting OF, Swanson, catcher. I'm not there yet since I want to see more of both this season, especially Demeritte to see if he continues to cut his K's, hold his power, hit for enough average and play great defense.
Either way (posi-Brave comment) it's a good situation to have.
