No i think your seeing some degradation in strength from Fredrick due to the Auto immune disease, i know someone that has this and once you have it under control your strength never comes back to 100% you have days were your 80 - 90 % and days were you are 70 - 80 % not to mention he's doing this over and over again over the 20 games schedule in the year. Then you have Martin, i do think he's got something going on with his knee or back but he's just off this year. and Conner is not a Guard in my opinion, he's a Tackle not strong enough in the trunk and lower body to be a guard, he would have been great in a Shanahan Zone running scheme but he's not in that, he's in our hybrid offense... get him moving on a zone read or pulling to second level and its a thing of beauty, but not able to just move straight a head with power and consistency.
