Well, since no one else is willing to be devil's advocate, I'll play:

I don't think the injury rate is crazy, well, maybe only a little.
But there are strings of injuries that can be frustrating.

I have too many teams (some on autopilot), so if there was a pattern to injuries you'd think I'd notice.
(first week/last week most injuries)
Also I have a pretty consistant rate through all my teams:

The INJURY rate should be decreased...-domi.jpg

The INJURY rate should be decreased...-ffb.jpg

The INJURY rate should be decreased...-crfc.jpg

The INJURY rate should be decreased...-beezz.jpg

The INJURY rate should be decreased...-stls.jpg

Rotate, never let them get below 70 percent in training, upgrade turf & med, assign some points to physical. Works for me. Domino FC's players are most like BvB's and they have super high physical, and it is my second oldest team... and they get the least injured.
Red packs aren't the problem for me... my teams are always are running out of BLUE.
