The kind of strength Martin needs cant be aquired in just one offseason in the weight room. You arent going to double your strength in 6 months.
As far as Jake Long goes, this is the first time I have heard that he was offered a contract mid-season. Too bad Barry Jackson doesnt say what his source is.
Who said he had to "double his strength". He can make a ton of gains in one offseason. It is not just physical training, but improving his technique on the field. I think Martin can be solid next year.
