Go take a look at Skinner over his career, there's a reason a team with tons of cap got rid of him. He hasnt just had cold streaks in season, he's literally had entire seasons where he sucked.
Again to be fair I shouldn't have said Sprong has been more consistent without saying the sample size is small because he's really only played a meaningful amount of games a handful of times but in the four seasons he played at least a half a season he's had 14 in 47, 13 in 42, 21 in 66 and 18 in 76 with the last two getting more assists than goals as well. While playing 1307, 1406, 1125 and 1205 minutes.
Skinner plays between 16-18 minutes a game. I hate extrapolating but Sprong has been more effective based on minutes and if he was given Skinners role would likely score a lot more goals.
I think a guy like Sprong makes way more sense on the oilers over Skinner, since you guys have an excellent top six but lack much depth scoring and that's always been an issue since your teams record when McDrai don't combine for 3+ points has been pretty abysmal.
