Richardson would be a TERRIBLE pick.
This team isn't good enough to use the 6th overall pick on a guy that will be lucky to take 30% of your offensive snaps.
I fully understand we need a #2 back and I fully understand the SJ39 is getting a bit older, but you have too many holes to afford that luxury at this point. Maybe in the second round. As a general rule teams are moving away from drafting running backs in the first round at all....so selecting a second running back with a top ten pick could single handedly be the absolute worst draft pick I've ever seen a team make in my life.
I think that Claiborne would be the best pick for the Rams. Their secondary was AWFUL last year. Justin King was the worst CB in the league. But I'm not sure he'll be there at 6. Stranger things have happened though.
I'm with cardsfan, I don't think Blackmon will be a superstart WR, that's a good way to put it.
I don't think Richardson would be an awful pick. Sure, he may take only so many snaps this year, but eventually the Rams have to have a contingency plan. SJ39 missed some time last year...and our secondary option was...Cadillac Williams. Not a terrible backup plan, but not really an asset either.
I think Richardson has the makeup to be a good back, but really, the Rams just need to get the best player they can get in that spot. Too many times the Rams have drafted for need and not picked the best player.
I have to study up on more of the people that are projected to go in the top 10, but those are the three I'm most familiar with aside from the two QB's and Kalil.
