I'm not so sure this year.
Bleis - too far away and the on field performance has been lacking
Castro - not losing sleep if someone takes him
Drohan - if selected for the 2nd time he doesn't come back, injury prone
Hoppe - could be a reliever at some point, but not reliable right now
Monegro - injured
Mullins - maybe, lots of injuries, probably selected though
Paez - ended the season injured and far away
Sandlin - similar to Slaten MiLB numbers, could pop but has been rough
Uberstine - depth starter, but not a guy typically selected
The two guys that there are decisions on are Mullins and Sandlin. I could see the Sox protecting either or trading either prior to the Rule 5 deadline. There are some issues with both. Everyone else are either unlikely to get drafted or would probably be returned to the Sox if they had to appear on a MLB roster.
