The 37-year-old boss moved to address Boyd's standing with the club at his unveiling, hinting that the forward may have to look at securing a move elsewhere if he wants to play regularly in the coming campaign.
The reasoning behind this seemingly tough stance is that Boyd's lumbering, target-man style may not be as conducive to adjusting to Porter's fluid style, with competition for places set to be fierce given that Portland already boast a wealth of attacking options including Nigeria international Bright Dike, Darlington Nagbe, Danny Mwanga and Ryan Johnson to choose from.
"Kris Boyd is a player that I think will have a hard time fitting in with this system," Porter told reporters.
"[Boyd] will have a hard time playing the way we want to play."
The 29-year-old's high salary figure (he made $1.25 million in base salary in 2012 according to MLS Players Union documents) has made him an unappealing trade target within MLS.
