There are lots of opinions out there as to which rookies will have an immediate impact this year. The popularity of fantasy football puts most of the attention on skill position players, but hardcore fans are just as interested in offensive linemen or safeties (or any other position) giving their favorite teams immediate and significant playing time.
I've featured several higher round picks like C.J. Spiller , Bryan Bulaga and Brandon Spikes already as players I fully expected to stand out as rookies and, at least in the preseason, have done so.
I've also listed 10 players drafted in the 3rd round or later who have impressed as rookies.
The following five players make up the exact opposite story. They are five well-hyped prospects who have thus struggled to acclimate to the NFL.
QB Colt McCoy, Cleveland: McCoy was recently among a list of eight players characterized by Tony Grossi of the Cleveland Plain-Dealer as "need[ing] good showings in the last two games to make the roster." McCoy, in two games, has only completed 5 of 12 passes for 25 yards. He's thrown two interceptions and taken two sacks.
RB Toby Gerhart, Minnesota: The Vikings were hopeful that Gerhart would win the 3rd down role behind Adrian Peterson. Gerhart's inconsistent hands and route-running is a concern. So too is the lack of foot quickness he's shown so far. Gerhart can help this team as a short-yardage specialist, but that may be it.
WR Armanti Edwards, Carolina: Edwards has flashed for the Panthers, but he's shown just how tough it is to switch from college quarterback to NFL wide receiver. He's had issues at receiver and punt returner and may require a "redshirt" year.
WR Golden Tate, Seattle: The 2009 Biletnikof winner, Tate has been a star in training camp, but in the games -- where he's needed to run crisper routes -- he's struggled to demonstrate the same playmaking ability. Tate will be fine. He's too talented not to, but he has only three catches for 13 yards in two games so far.
RB Joe McKnight, New York Jets: I remember when McKnight signed with USC out of the state of Louisiana as one of the most hyped prep prospects in the country. He never showed the agility and balance of Reggie Bush -- the guy he was signed to replace -- at USC though, at times, he received similar hype. McKnight is a terrific athlete, but I haven't seen the toughness out of him so far to think the Jets can keep him on the field much this year.
