“It’s an awesome feeling. Speaking on behalf of both of us, we’re pretty keen and excited because we’ve got such a bright future,” Coffield told saints.com.au.
“We’re looking forward to hopefully improving as individuals and as a club over the next four years.”
Clark was taken at pick seven in the 2017 draft and made his debut in round one against Brisbane and recorded 12 disposals and kicked a goal.
Coffield, taken at pick eight in last year’s draft, debuted in round three against Adelaide and showed promising signs with 18 disposals, six marks and goal.
18-year-old Coffield has been raising awareness for the anti-coward punch charity, the PC12 Foundation, established after the death of Patrick Cronan, a close family friend of the St Kilda midfielder.
“Our family’s pretty close with them, so to create a bit of awareness around them I put ‘PC12’ on the back of my boots because it was his two-year anniversary yesterday,” he said.
The Saints host the Giants on Saturday afternoon in round five.
