Fascinating read through and data regarding the real world NFL and injuries. The link is part 4 of 4 and each part is worth a read.
NFL Injuries Part IV: Variation by Positionhttps://www.footballoutsiders.com/stat-analysis/2015/nfl-injuries-part-iv-variation-positionFWIW: Injuries are just fine in MFN, they really are. Data shows MFN is close enough, anyway. My 2 cents is y'all's fatigue settings are way, way too low. If 60-70 is "suggested," WHY use 25? I use overrides to get the right player in the right spot, perhaps a high speed/acc guard for a pull running play, high spd /acc/pass rush for a blitzer only position in a formation, and never for fatigue purposes.
It is rather challenging to get a proper perception of just how injured a player is, but I also do not play any player with an injury rating of 65 or lower in a key appendage ie a foot/knee/ankle for a wr/rb, or neck, ankle feet for linemen, etc. Be super nice to know which side - left or right.
The decreases in spd have been discussed to the very best guesses any of us can give from the work put in, max 25% decrease. So, a 0 is 25% decrease. I don't know about you, but if my leg is at 0% I am surely not even walking - and yes call me shirley :P The point is, it should be fair to extrapolate that persons findings and say a 50 hand injury is a 12.5% decrease to catch the ball?
The truth is, despite the community's vast and much appreciated efforts, no one knows jack about the absolutes to be able to make a confident decision about something as simple as if an injury should result in benching a player for a game or be placed on IR for the season.
In addition, there's always <10 other players not showing an injury designation that do have injuries. We all ignore them though, because we don't see the word "probable." Someone called them "hidden" injuries a while back and thought it was a bug. Totally innocent question, but hilarious and shows just how much we ignore the data we don't see or know of.
That thread included someone asking which player to play, and someone suggesting to play the more injured player. Who in there right noggin would play a player at a position who is more injured just because the player rating is higher?
In conclusion, I'm not going to say I know the answer, I will say I think many people have taken the idea of injuries more seriously than necessary as a direct result of a real lack of what the numbers on a player card actually mean.
