By posting those stats I didn't necessarily mean to imply that Compher is miles better than Bennett.
Rather, I was simply illustrating that a comparison between the two is much closer than what
@Nanuuk suggested by only hand-picking a select few stats that were all in favour of Bennett. Both players have positive aspects, and both players have negative aspects.
I think it's fair to say that Compher is a better all-round player given his point production and play on special teams, but that Bennett has unique skills and intangibles that make him valuable as well. Overall their trade value is pretty close, and that's why both sides keep bringing it up as a potentially fair trade for both teams.
