For my team, I first do physicals. 18 min strength, but I prefer 19 or 20. No min speed for C or OG, but I like my OT position to have 15 or above speed, not sure it does anything, but in my head, I like the speed to contain fast DE's. Once I've reached min fitness I like to train skills evenly with blocking first, then footwork, then agility, then tacticals (both vision and position). This would be the 5 skills I train for all the OL positions. Since all players use 3-5 skills, I feel pretty comfortable that these would be the maximum possible skills used for this position. If I'm training too many, that's okay too. I also haven't found the need to train OL over skill of 14, as my team stays pretty competitive as is and it helps to keep finances in order. Lastly, I bring the stamina up to 16 to keep my guys blocking into the 4th quarter. Hope that helps
