PITTSBURGH -- When the Pittsburgh Steelers drafted Sean Davis in the second round last spring, defensive coordinator Keith Butler reveled in the possibilities.Here was a 6-foot-1, 202-pound guy who could play both safety and cornerback depending on the situation, someone with the size and the speed to keep up with -- if not totally neutralize -- players like New England Patriots tight end Rob Gronkowski.Davis may very well develop into such a player, but hes not there yet.You would like to think we could put him on Gronk and say we got him, Butler said. I dont think anybody can do that.Particularly on the NFLs 30th-ranked pass defense, one that faces Gronkowski, Tom Brady and the rest of the NFLs most diverse offenses on Sunday when the Patriots (5-1) visit Heinz Field. Bradys lit up the Steelers for 24 touchdowns against just three interceptions in 10 career meetings with the Steelers (4-2), most of them against variations of the Steel Curtain that were far more imposing than the current iteration, one rife with inexperience, particularly in the secondary.The growing pains have been evident. Davis has seen his playing time fluctuate and didnt play one defensive snap in last weeks one-sided 30-15 loss to Miami . He may not get back in the lineup this weekend either. Cornerback Artie Burns, a first-round pick, is improving but still very much a work in progress. Special teams ace Rob Golden is in his first year as a starting safety and his main backup is Jordan Dangerfield, a former practice squad player.Throw in linebacker Ryan Shazier -- like Gronkowski a physical marvel -- and the balky knee thats kept him out of the lineup for a month plus a pass rush thats been more rumor than fact in Pittsburghs two losses (zero sacks) and the prospect of facing a dominant Brady seems like a mismatch.We need to play more than one defense against these guys, Butler said. Theyre very good. They can pick you apart if they can figure out what youre doing.Its finding the right looks to throw at Brady -- who has pretty much seen everything -- and the right people to put in the right places thats the problem. Then theres the issue of youthful exuberance. With so many fresh faces, the lure to try and go above and beyond while facing the NFLs top tight end and a Hall of Fame quarterback is only too real.Its tough sometimes, Shazier said. Guys want to make plays. Youre playing against one of the best guys and you want to see how you relate and everything like that.Shazier sees it happen regularly to opposing defenses trying to figure out what to do with Steelers All-Pro wide receiver Antonio Brown.Guys come up with a game plan to stop AB and when youre not sound enough, he destroys you, Shazier said.Its the same with Gronkowski, who set a career high with 162 yards receiving last Sunday against Cincinnati. Having Shazier back may help. And the Steelers are at least a little bit bigger -- if not necessarily better -- than the group that allowed Brady and Gronkowski to hook up for three scores in New Englands 28-21 victory in the 2015 opener. Burns is 6-feet tall, as are cornerbacks Ross Cockrell and Justin Gilbert.While thats still considerably smaller than the 6-6, 265-pound Gronkowski or the 6-7, 248-pound Martellus Bennett, its a start.I think it goes back to being disruptive, said Cockrell, whos had moderate success this season against bigger receivers like Cincinnatis A.J. Green and Brandon Marshall of the New York Jets. Were going to be able to put our hands on some of these guys and disrupt them and disrupt their timing.Davis is hopeful to get in on the act. He understands why hes not atop the depth chart. On a team with lesser ambitions, maybe hed get to play through the mistakes. Not so on the AFC North leaders.I cant complain or mope, Davis said. Ive got to handle my (role).One that will continue its evolution on Sunday in a game that will be as much about mental and physical discipline as it is simple talent.If you abandon your job and help somebody out or try to be selfish and make a play when you really shouldnt, theyre going to capitalize on it, he said. When the plays come your way, youve got to makeem.Game notes Shazier practiced Thursday and is hopeful he can play. Golden (foot) and S Mike Mitchell (knee) also practiced for a second straight day. ... T Marcus Gilbert (ankle), WR Markus Wheaton (shoulder) and RB DeAngelo Williams (knee) did not practice for a second straight day.---Online:AP NFL website: http://www.pro32.ap.org and AP NFL coverage on Twitter: http://www.twitter.com/AP-NFLCheap Dennis Eckersley Jersey .

Hes an excellent fighter with the right work ethic to become world champion.Rico is tough [against Horn] and he knows the challenge in front of him, but hes a tremendous talent and I see him rolling along to an impressive victory.
