It will be interesting to see how they use Benny Sko over the long run. I think he's primarily a STs player this year. But give him a year to polish his route running and blocking technique and he has the potential to be that lead blocker they want next year. Also, he would make a very nice addition as a possession receiver for Stafford. With the WRs the Rams have they will begin to see a lot of zone coverages especially next year when Tutu & Harris make their speed felt. Benny is versatile enough to be a lead blocker and possession receiver against zone coverages. As the film shows he isn't afraid to make those contested catches, something Reynolds never really mastered.
In the long run, I can see Benny Sko as a good rotational receiver who can block on early-down runs or be a factor on early-down play action. I can see Jefferson eventually taking over for Woods, and Tutu becoming that Jackson like slot receiver.
