I'd suggest using z-scores rather than raw totals. Puts everything on the same scale. 5 PPP are much more significant than 5 SOG. It then becomes easy to just sum the z-score totals for each player to get an idea of the talent at the top of each position. You can also run a few iterations on the whole pool of players and find out who the best 14 are at each position rather than just using the top 14 drafted, which are almost always not the best 14 players.
Z-scores are calculated as ("X" - Average)/Standard Deviation. It's a really simple calculation and gives much better insight into the numbers. Also, you can do conditional formatting and colour-code everything at once since they're all on the same scale.
Generally all forward positions should be treated the same, especially if there is a utility spot. Replacement level for LW, RW, and C is almost certain to be the exact same. If your league mates are putting extra value on RW or something, I'd suggest to zig when they zag, and grab the elite guys at the so-called "deep" positions, and settle for the lower tiered players at "shallow" positions. If your'e in a really shallow league like 10 teams and only 6 forwards per team with no util spots, then you start to run into position scarcity, but I get the feeling most people doing this type of analysis are in deeper leagues like 12+ teams with 9+ forwards per team.
