I think Petan will be able to fit in with the cheap bottom-6 that the Leafs will inevitably need to have in the next couple of years in order to keep their core intact, and will bring more overall than Lindholm. Leafs' bottom-6 will be on average less than $1M per player overall (assumong Johnsson re-signs and Hyman/Brown are dealt)
Leafs top-7: Matthews, Marner, Tavares, Nylander, Kadri, Marleau, Kapanen (about $52M)
Leafs bottom-6: Johnsson, Moore, Petan, Gauthier, Bracco, Baptiste (about $5.5M)
