"Being with Peter in Boston, what he was able to do with us there, adding the right pieces at the right time and my loyalty towards him made the ultimate decision and I'm just excited to get going and see what we can do moving forward," Lucic said on Sportsnet.
Lucic said the opportunity to possibly play with center Connor McDavid and the other young Oilers forwards was enticing.
"Now I get another opportunity, whether I'm on his line or not, to play with a great player here, whether it's McDavid, [Ryan] Nugent-Hopkins or [Leon] Draisaitl," Lucic said. "They're all really good centermen. My abilities goes further than just the intimidation factor. I believe in that and that's what I know I can bring to the Oilers.
"I think the Oilers have been missing a little bit of attitude and a little bit of swagger over the last couple of years, and that's something that I bring to a team as well. ... I'm excited for another fresh start as well."
