Look at it like this..it takes BOTH Justin Smith, AND Alden Smith to get the job done right, and by themselves, each are Pro Bowlers.
I love Irvin, BUT, he ain't going to get it done all by his lonesome, it's going to take an upgrade on the D-Line if we want to see him reach his potential sooner, rather than later, and I trust that Pete Carroll and John Schneider already have plans to address this in either FA's or the Draft.
Yes . . . But Aldon Smith and Justin Smith don't play the same position, do they? Which is exactly my point.
