Yeah in fact after I typed that up I thought I missed something because I didnt remember carry an extra OL guy. So I went home and checked my players,
Here is how I did it
QB 3
HB 3
FB 2
TE 2
WR 6
LT 2
RT 2
C 2
LG 2
RG 2
Off total 26
RE 2
DT 4
LE 2
ROLB 2
MLB 2
LOLB 2
CB 5
FS 2
SS 2
plus 1 additional LB or defensive linemen
Def Total 24
K 1
P 1
Total team of 52
You can also minus the additional line backer if you want to use 51. After year one in my franchise I will run with a additional OL men and 6 LB's. If I need to sign someone I will do so for only 1 year depending upon the injury and weeks the player will be out.
It works for me and helps me get around the IR issue, but as I said may not be for everyone. Hope this helps somewhat.
