LATROBE Jason Taylor Jersey , Pennsylvania -- The thunder of padded practices earlier in the week was a faint memory by the time Wednesday's practice rolled around. The ' second-to-last practice of training camp was a thinking man's practice, as Pittsburgh's players worked through situational drills while leaving their pads inside the locker room.Wednesday's practice was the continuation of several notable position battles. Inside linebacker likely helped his cause in his position battle with when he recorded a pick-six off of during team drills. All eyes continued to be on the ongoing quarterback battle and specifically rookie quarterback , whose practice Wednesday showed that, while he is showing considerable signs of progre s, old habits do indeed die hard (more on that later).The afternoon's practice also reinforced the fact that a capable receiver will be left off the team's initial 53-man roster. Several promising wideouts are vying for the final two spots on the depth chart entering the Steelers' second , which will take place Saturday night against the . receivers working on their toe taps. BryanDeArdo (@BryanDeArdo) Everyone can agree that, barring injury, the following players will lead the Steelers' receiving corps at the start of the regular season: : The team's No. 1 receiver who is coming off his first Pro Bowl campaign and multiyear extension. : While his 2021 season did not measure up to his rookie campaign, Claypool still has tremendous upside and potential. : The rookie second-round pick will be a heavy contributor to the offense, po sibly right away. : If healthy, Austin's versatile skillset will be put to use by offensive coordinator Matt Canada.With the top-four spots solidified, here's a look at the receivers who have the best shot at earning one of the final spots on the roster.The front-runner to earn one of the final receiver spots on the 53-man roster. NFL Miami Dolphins Jersey The former All-Pro returner enjoyed a solid debut with the Steelers during Pittsburgh's preseason-opening win over Seattle. He seems to have developed a rapport with each of the Steelers' quarterbacks, which was on display on Wednesday as he continued to be seen on the receiving end of pa ses."He's adaptable," Tomlin said of Olszewski following practice. "He's versatile. He plays multiple spots. He's tough. I can't stay enough about the toughne s that he displays." PIT WR #89 Olszewski actually came down with the most impre sive catch practice. Pickett, under dure s, rolled to Jason McCourty Jersey his left before lofting the ball over a defender and into the out-stretched hands of Olszewski on the near sideline. But while Olszewski's catch was impre sive, Tomlin was more focused on the quarterback who threw the pa s."Gotta get that ball out," Tomlin said to Pickett, who is known for holding the ball a bit too long at times.A former undrafted rookie, White is entering his third year with the Steelers after having short stints with three other at the start of his pro career. He spent his entire rookie season on Pittsburgh's practice squad before appearing in 15 games last season. White made an impre sive catch Wednesday on an equally impre sive throw by quarterback . Sims spent his first two seasons in Washington before spending the majority of the 2021 season on Pittsburgh's practice squad. Sims made a pair of splash plays in last Saturday's win over Seattle that included a 38-yard punt return and a jet sweep run that also picked up 38 yards."He's working extremely hard," Tomlin said of Sims, who caught 61 pa ses in Washington while also returning a punt for a score. "He's working to define a role. He's a guy that's fighting for a seat on the bus." PIT WR #82 Sims is not familiar with John Taylor, another receiver/punt returner who wore No. 82 while helping the win three Super Bowls. Sims was familiar with another No. 82 that helped the Steelers win their fifth Lombardi Trophy back in 2005. "There's a lot of greats Robert Jones Jersey that came before us here that put the uniform on," Sims said prior to Wednesday's practice. "(Number) 82 especially. (Antwaan) Randle El, I was watching 'Hard Knocks' yesterday, seeing him. There are a lot of greats that came before us, and we've got to live up to the name."The former receiver is a big-bodied po se sion receiver who hasn't nece sarily stood out during camp. His pedigree (he's a former third-round pick of the Ravens who caught seven touchdowns in his first two NFL seasons) might give him a slight edge in the position battle.The recipient of last Saturday's game-winning score, Vaughns has showed flashes of his potential during camp. He also oftentimes comes up just short of making a big play during Myles Gaskin Jersey practice. While practice is still important, the remaining preseason games will ultimately determine which receivers will earn the final roster spots, and which ones will be vying for a spot on Pittsburgh's practice squad when the page turns to the regular season.
