Quoting: Hammerwise
That quote while statistically correct doesn;t address the difference in teams, team philosophy, team production or state of the team (rebuild/contender/etc...) or anything else, and as dannibal pointed out above, its NOT that Kerfoot doesn;t have value or is a scrub, hes not, but what does he bring to the other team and why would they want him? Of course STL would take his cap hit to make the deal work, if they like the other pieces, but the player himself has no value to STL if they are tearing it down.
PHI, for instance has a lot of cap space and could act as a dumping ground, but they wouldn;t take say kerfoot for a 3rd, because kerfoot has no real value to them this season or moving forward. So they'd view Kerfoot as a negative or neutral asset at best and want to be paid for taking him, ala Marty Murray.
IMO, Leafs need to keep kerfoot if they can, hes their best option for offense on that 3rd line. Teams that would want Kerfoot or could view him as a positive asset are probably similar playoff bound clubs, who are also looking for an upgrade so probably wouldn;t offer an equal player.
Your analysis was excellent until the part where you said that the Leafs would have to add something for the Blues to take Kerfoot which implies a negative value.
If we merge and consolidate, between the things said by you, drewjenkins, and dannibalcorpse, what we get is: Kerfoot is just a cap component that most if not every team looking to add O'Reilly will have, he's neutral in the trade so wouldn't require any additional asset for being in there. However, let's just assume that the Leafs are giving the best offer, but there's another team with a similar offer but is only giving futures OR giving a cap component with term OR an expiring ufa that is more/less useful than Kerfoot, then whether or not Kerfoot tips the scale in the Leafs' favor or they are asked to add to beat the other offer depends on the Blues preference which could be different depending on if they still have an outside chance at making it or not (they could be sellers and buyers), or if they would just rather tank if they sell.
Same applies to the Meier trade (they might not mind Engvall at all, no reason for them to take Gaudette though, or the Leafs to even trade him). The biggest issue here is the light offers, maybe the Leafs manage to get one guy (I would assume that it would be O'Reilly if I was told one of those mock trades actually happened) but the chances that they get two top "rentals" with low offers are slim to none.
