...fan. The only red flags to worry about are the following,
1.injuries, only deplete depth and if it happens to key players, can be devastating.
2. Getting physically WHOOPED! Scores and winning the game are pointless....but you don't want to see you team get "out physicaled" especially on the OL and DL. Defenses and Offenses will be very vanilla, but getting physically whooped can be a negative carried into the regular season.
3. Special teams, poor special teams play can and will carry over to the regular season, think about it, the guys you see on SPT's are the "starters".
