The Steelers' need @ RT is more immediate than @ LT. Both guys were impressive toward the end of the season and in bowl games, but where Williams looks to be more of a pass protecting LT prospect (who needs to get stronger and doesn't play as physical as he could), Cherilus is a prototypical RT prospect who only played LT last year out of need and fits the Steeler mentality to a T. I believe that if both were available w/ their pick, Cherilus would be their choice.
