That's okay, you can't give them all ELCs and Tyszka's development curve just didn't go up enough ( injuries and bad luck didn't help obviously) . Hopefully he doesn't come back to bite us at some point but I doubt he will TBH.
Sad that no team was willing to give up even a 7th round pick for either one of them, the Habs probably made the right decision not to waste a contract spot for 3 years for either Tyszka or Walford.
