Kylington clearing is a dunce move by the rest of the NHL. You'd think a team would take a flyer on him, especially the Bruins who aren't exactly stable in that position.
I think a few more coulda been claimed (Frolik, Chlapik, Svechnikov, Merkley, Jaros and maybe a couple more) but these 4 absolutely SHOULD have been claimed and the fact that they cleared is extremely surprising.
