I may be wrong, and perhaps they'll only add 3 today, that's fine.
I guess I'm just suggesting that *if* they don't add any beyond the obvious 3, it says something about the guys they do NOT roster. It means some low-risk internal evaluation. It will mean they either don't think the player(s) will get taken/kept/lost, or else they don't evaluate the players as being significant enough to mind losing them much. You hope you don't lose Correa or Sanders, but hard-throwing wild relievers are not rare. Assuming they don't protect Jensen, it kinda reflects that either they don't expect he'll get taken anyway; or if he is that's just the way it goes, it's not like they really expect him to become more than an inconsistent wildman reliever anyway.
So, in a sense, it's maybe slightly revealing: *if* they keep an extra guy or two, it means they are pretty interested. And *if* they hypothetically don't, it's maybe a little disappointing in that it means they probably don't believe in the guy too much.
