It’s understood Scott, who stepped down as North Melbourne coach in May, has been left mentally and emotionally drained from the aftermath of his departure from Arden Street.
But he’ll have no shortage of suitors is he is open to offers.
Carlton will have the first opportunity to speak to Scott, given Richardson is contracted until the end of 2020.
But even if Richardson does survive the season, it would take an almighty backflip from the club’s administration for him to remain the Saints’ coach next year.
So unless Carlton act quickly and hire Scott before St Kilda have a chance to engage with him, it puts the former Kangaroos coach at the top of the market to be coaching at Moorabbin next year.
Not far behind is Brett Ratten, the man that was sacked as Carlton coach and is now working under Richardson following time at Hawthorn with Alastair Clarkson.
Ratten is loved by the Saints players and has publicly thrown his hat in the ring to be a senior coach again.
St Kilda is also likely to reach out to premiership-winning Western Bulldogs coach Luke Beveridge.
Lethlean was criticised on Sunday for sitting next to Richardson in the coach’s box during the Saints’ clash with North Melbourne in Tasmania, despite the fact he’s sat in the same spot several times before.
“When they kept flashing to the coach’s box to Alan Richardson, it’s not often you have the footy manager Simon Lethlean hovering on his shoulder. He is the man who is probably going to be in charge of the coaching panel they put together,” Jimmy Bartel said on Macquarie Sports Radio.
“When you look at Alan Richardson, he’s got improvement out of the young players and improvement out of some mature players that have been just going in the last couple of years, and some mature-age recruits.
“The one factor which worries me for Alan Richardson is he’s been there for six years without playing finals.
“If you’re going to keep him as coach, you’re not going to keep him for next year, you’re probably going to renew him for a couple years and that’s where St Kilda are (weighing up) their decision making. Do we go this long with this guy?”
Carlton officials have remained extremely tight lipped as they embark on their search for a new coach.
Although Clarkson has both publicly and privately laughed off speculation, it’s understood that the Blues have not given up hope of landing the four-time premiership coach and he remains their top priority.
Fremantle’s Ross Lyon will also be approached, but he too has publicly committed to his current club.
