Coach Bruce Arians called his quarterback's first eleven on eleven action since sustaining a season ending knee injury last November "outstanding." Arians didn't expect to have his quarterback return until training camp, which is still seven weeks away. Palmer confirmed he was wearing a knee brace under his pants and he will continue to do so. Having knee surgery in 2006 on his right knee helped Palmer know what to expect this time around. Palmer says his recovery has been exactly the same and he knows what to do Collin McHugh Jersey . That's why he's in a better place this time. still looks as strong and fit as ever, but the chemistry building between Palmer and second year wide receiver was on full David Price Jersey display, especially on deep routes. "I expect huge things from him this year. There is something different about him," Palmer told me after practice. Word around the building is that his Brown is stronger, in better shape and people are taking notice of his work ethic. (Wide receiver sat out with a tweaked hamstring) Carson and Brown will continue working together after this week's minicamp ends. Brown will work out in San Diego with Palmer. players take note. Palmer called Eduardo Rodriguez Jersey the offensive line's protection phenomenal, but it's Arizona's ability to run the ball that might most help Palmer elude pre sure this upcoming season. Arizona ranked 31st running the ball in 2014 and too often didn't have enough balance on offense. Running back is 100 percent after mi sing the end of last season Rusney Castillo Jersey with a hip injury. Rookie third round draft pick is a bigger, heavier, grinder and should bring a change of pace to the running game. He's already spent some time working with the starters.
