I reckon this is a likely result for the Saints withstanding a slider like Stephenson/Cerra (unlikely). It would be a good one too, would love either at 10.
I don't think Bonar is the right choice, seems a similar type to Steele. Both Coffield and Clark have the versatility, speed and kicking skills that make a perfect fit with both likely to start off a wing or HBF. The key is whether you think they will transfer into the midfield full time as they develop, Clark being more likely to do so IMO. If they both do then you're laughing.
With the Saints well placed in the draft, it's going to be an exciting year next year.
Good luck on Friday, can't wait for "the slider" to reach pick 10 and come to Carlton.
