Illinois RB Rashard Mendenhall is likely to get 6-to-10 touches per game as a complement to starter Willie Parker in his rookie season, and he eventually could unseat Parker for the lead role. Mendenhall and Parker are roughly the same height, but the rookie is more muscular. However, like Parker, he is best in space and has exceptional straight-line speed. Mendenhall had moments at Illinois where he looked like a blue-chip back in the making, especially in his junior season, but he must prove he is more than just a one-year, spread-offense wonder. Nevertheless, his upside is considerable, and the Steelers had to be surprised he was on the board at No. 23. Texas WR Limas Sweed is a prospect who, at the least, could be the big receiver Ben Roethlisberger has missed since Plaxico Burress left. Sweed is capable of more than that in time, though, and could push for a starting role by his second season. UCLA DE Bruce Davis will likely convert to outside linebacker in Pittsburgh’s 3-4 defense. Davis can get to the quarterback — he finished his collegiate career with back-to-back double-digit sack seasons — but he’s not strong vs. the run, so he may see most of his playing time early in obvious passing situations. Texas OT Tony Hills is a converted tight end with good athleticism, but he has battled a history of left knee, foot and leg ailments. The Steelers’ next pick, Oregon QB Dennis Dixon, is coming off a torn anterior cruciate ligament in his left knee. He likely is to be the Steelers’ No. 3 quarterback this season and could eventually replace Charlie Batch as the backup. Dixon has a strong arm and moves well, but he needs time to develop as a pro passer. Iowa LB Mike Humpal projects inside in the Steelers’ scheme and will need to play well on special teams to make the squad. West Virginia FS Ryan Mundy could stick on the roster with a strong training camp.
