MacTavish reached out to St. Louis (Brian Elliott), Washington (Michal Neuvirth), Buffalo (Ryan Miller) and Anaheim (Jonas Hiller) over the past week, but a trade he did not find.
Instead, the Oilers are looking to bolster their blueline and get their hands on a gritty, two-way forward.
It's unclear, at this point, whom the Oilers are targeting. It's believed the Sabres are willing to deal forward Steve Ott, for the right price, and he would certainly assist the team in the toughness department.
The Florida Panthers are reportedly shopping the likes of Tomas Fleischmann, Kris Versteeg and Scottie Upshall, though Upshall is the toughest of the trio.
In order to obtain a top-pairing defenseman, the Oilers will be forced to trade one of their younger stars, and it appears Nail Yakupov is the most available. However, MacTavish refuses to trade the 2012 first-overall pick without a young star -- presumably a defenseman -- coming back to Edmonton.
