“As a highly regarded player who was still under contract at the Crows, we were fully aware it was going to take a lot of negotiating to get the deal done, so we’re delighted to come away with this result and appreciate Adelaide and Sydney’s cooperation throughout the process,” Carlton’s GM of List Management and Strategy Stephen Silvagni told carltonfc.com.au.
“Mitch has been a terrific player for the Crows over the past three seasons and we believe he’ll strengthen our forward line and add another layer of depth to our emerging list as we head into the next phase of our development.
“He’s got a great pair of hands and we’ve all seen how accurate he is in front of goal, so we’re excited to see what he can produce alongside our young forwards that we’ve drafted in Charlie Curnow, Harry McKay and Tom De Koning.
“After going to the draft for the past three years, we’ve been vocal about our need to start recruiting players within that 23- to 27-year age bracket and Mitch fits that profile. At 23 years old, he’s got a lot of footy in front of him and we hope he’ll be a long-term player for our club.”
