GLENDALE, Ariz. -- A daily review of the hot topics coming out of Arizona Cardinals training camp:
Justin Bethel's ascent up the depth chart continued Wednesday. With Antonio Cromartie out with a pectoral injury, Bethel was part of the Cardinals' nickel and dime packages. He played wide corner in both schemes, with Jerraud Powers playing nickel back. In base, Powers has filled in for Cromartie at corner opposite Patrick Peterson. Bethel had an interception late in practice and showed his speed weaving between offense players. Bethel might have made the most improvement among his teammates this offseason and it should pay off with more opportunities to earn playing time.
Even though he’s dealing with a calf injury and didn’t dress for practice, Lyle Sendlein played center for Carson Palmer during 7-on-7 drills. The more Sendlein can continue to work with Palmer during non-contact drills, the more they can keep up the connection they’ve developed over the past year.
During an early drill, Bruce Arians called over Peterson and discussed arm and hand placement during press coverage. Even though Peterson just signed a $70 million extension, he’s not immune from a little coaching.
All of Arizona’s tight ends have looked good during camp thus far. Rookie Troy Niklas, still playing with a soft cast on his right hand, made an impressive catch for a touchdown through three defensive backs.
