Around and around we go. It is clear that you buy into those stretches of brilliance that Bonifacio has had when his BABIP has been well above every other part of his career. I don't. That is the sum of this debate. You can choose to slice it how you want, but there is a reason not a single projection out of ZiPS, Steamer and Oliver have him matching those .262/.320 career numbers next year.
What bothers me is you're throwing out data when it benefits your argument. That's the definition of cherry picking. I used his career stats which is the good and the bad for both and Bonifacio had a .262/.322/.340. His one good season is something that happened. You can't just throw it out. And it's not as though he's never had other stretches like that as I've pointed out. If you don't want to buy his career stats than fine. But stop acting like they aren't a valid reason to believe in him. You're choosing to weigh some portions of his career heavier than others. Fine but there is significant data to suggest that he is more than marginally better than Barney offensively.
Hell, I can make the argument alone that Bonifacio is a better play on upside alone where as Barney doesn't appear to have any. But, I don't have to. The level you're suggesting Bonifacio will play at is higher than what Barney has played at offensively for the majority of his career. In 3 of Barney's seasons he's failed to put up a .300 OBP. So even if Bonifacio puts up .252/.303 that he did in his first full season in the majors it's still better than the .241/.294, .254/.299, .208/.266 Barney put up in 2010, 2012 and 2013. As I said, Bonifacio's floor is around the level of Barney's ceiling. Now there are other factors such as defense but we're talking the absolute worst case for Bonifacio being better than what Barney put up last year offensively.
As for using projections to justify your argument, perhaps you should look at what they projected last year.
Barney
Zips - .273/.311/.352
Streamer - .275/.315/.362
Oliver - .265/.298/.336
Bonifacio
Zips - .263/.326/.347
Streamer - .263/.324/.351
Oliver - .272/.330/.351
Point here being they are projections are far from accurate. Bonifacio had a down year and they are reacting accordingly. And even then you're grasping at straws. Zips has Bonifacio at .258/.315/.339, Streamer at .255/.318/.337 and only oliver projecting him where you seem to think he will be at .247/.294/.314 with a .311 BABIP which is well below the other projections and his career average. On the contrary, they have Barney at .253/.299/.349(-.019 OBP), .248/.300/.344(-.018 OBP), and .233/.291/.336(-.003 OBP). My entire point to begin with was that Bonifacio was likely to be 20-30 points higher in OBP and 2 of the 3 have him at 18 or higher so my 20-30 points higher argument was a whole 2 points off those 2 projections. Plus there's still no reason to believe Barney gets any better. Literally the only argument I'm seeing is to hope for his BABIP to rise. But even if it goes back to his career average you're talking about a player who is still a similar level to Bonifacio's worst case offensively.
Frankly, if it's not Bonifacio it will probably be Valbenua or Roberts or Murphy taking his job. I'm by no means saying Bonifacio is special. I'm saying Barney is that terrible.
