Peterson, Rea and Garrett almost certainly don't make a playoff roster if the other guys are healthy. I think Assad would likely be next on the cut list if the others are healthy, maybe Steele depending on what he looks like out of the pen.
Ben Brown has a chance to be an absolute weapon if he can be healthy. Cabrera is a complete wildcard. Could be one of our 4 best starters, could work out of the pen, could be off the playoff roster entirely
