Earlier today, the Leafs announced the first of what one presumes to be many deals leading up to the trade deadline. Shawn Matthias has been traded to Colorado for 22 year old AHLer Colin Smith, and a 4th round pick in the upcoming 2016 NHL Entry Draft.
Matthias was one of many Leafs who were acquired this offseason on short term contracts (1 year, $2.3M in his case), seemingly with the intention that the Leafs would trade them later in the year. That's exactly what's happened here, and the Leafs get a pseudo-prospect and a pick as a result.
