I was just wondering if anyone knew if there was a site that measured the amount of time players spend in a particular position during the season and calculate the PER and all other stats (shooting percentages etc.)? I was just wondering because it would be very effective tool to gauge player performance for those players who are forced into positions at which they are less suited to like; Afflalo moving to SF so that Redick gets to play at SG. In this way we can make a better comparison of player performance against their natural opponents and make better judgements at who is the better player and by how much. Despite feeling that Redick in this season is superior to Afflalo (contract year, career year who knows?) I think Afflalo's numbers are suppressed by being forced into significantly unfavourable match ups on both the offensive and defensive ends, and was curious to see if this is true and to what extent.
Any help is greatly appreciated.
