Sure, but the guys with the ability to play in the NFL are not often the guys being counted on to do that blocking. If they are running a WR screen, they are the guy they are getting the ball too. And, out of necessity the blocking schemes aren't as complex. So, while they may do it some, it's not as important or as much as will be required in the NFL.
I also think the number of spread offenses in college are why there seems to be a lack of talent on the OL in the NFL in general. Most teams have decent starters, but finding good backups is very difficult. It's probably part of why spread concepts, RPO, and Read Option have moved from college to the NFL and become relatively common in the NFL.
