Those are the best players from each of the last 5 drafts. They are also the core of this team & untouchable. Anyone else is expendable; Davis, Johnson, Kalil, Olsen, Williams, Stewart, etc. They're all replaceable, & watching how Dave operates I'd assume will be replaced sooner rather than later. The 5 guys listed above aren't going anywhere for the next 4-6 years. They are the pillars of this team.
Kalil is expendable??? Id personally put his value FAR above Kelvin (man hasnt even played a single down yet in the NFL) and even Star. Hell, if we cant even get respectable help for the O-line mess we have now...how is Kalil (you know, a 3 time pro-bolwer) expendable and replaceable given our current situation?
