Just to refresh, I'm taking a look at the best players in the draft, based upon their presumed draft order, without trades. We all know the stats, so I'm not going to bother with all that. Also, this is from the Rams perspective, not the league as a whole. So onto the reasons to take Morris Claiborne.
First, he seems to be the best CB in the draft. With Bartell breaking his neck in defense of the arch (?) and coming back...and Bradley Fletcher having very circumspect knees...it's hard to tell. Some have made the argument that he's not as good as Patrick Peterson, who came from the same school. This is certainly true. He's not. However, I know Bradley Fletcher is rehabbing diligently. I know that Bartell wants to try, despite advice otherwise.
I don't know how anyone can call this a position of strength. I would love to think that both will be back at full speed, but we cannot count on that. Even if Bartell comes back (which, imo, is absolutely crazy...he must have spent all his money) he's getting up there in years. You broke your neck dude. Invest in a mutual fund.
The Rams have the luxury of a great deal of depth from last season from their cornerbacks. This is the legacy of Spags. He also did will with the lineman.
At the end of the day, Claiborne is a luxury, not a necessity.
