I was also surprised when Tim Hightower mentioned to me that the most of the strongest guys on the team "are not ones." Meaning they aren't the starters, but backups or 2nd or 3rd team guys.
This is of course the case many times with athletic teams, the best athletes tend to be the genetically gifted elite and many of them do not have the same work ethic in the weight room of some of the less talented. They "show" their strength in the weight room better, because they practice lifting weights more.
The guys who are the strongest, work very hard so that they can actually MAKE the 2nd and 3rd teams. They make up for less gifts with raw work ethic and strength. Had they not done this, they likely wouldnt be on anyones team to begin with.
