Swain's struggles included poor route running, ball protection and dropped passes all noted by the media.
Quarterback Aaron Rodgers threw only one interception on the first day of training camp, but the blame went to Swain.
"He threw the only interception of the day, but it may have been a mistake by Swain," writes Rob Demovsky of the Green Bay Press-Gazette. "During the morning practice, Swain ran an out route, but Rodgers threw inside, where Al Harris picked it off."
"Swain, the rookie seventh-round draft pick, had another hands issue, getting stripped from behind by Will Blackmon after a catch during 7-on-7," reported the Press-Gazette during the night practice.
Furthermore, Swain also "mishandled a Brohm pass" in a case of the drops.
As for Pat Lee, don't look for him to win any punt return duties.
"In two chances, he whiffed completely on one punt and the next bounced off his chest," reports Tom Pelissero of the Press-Gazette.
Pass coverage was a sore point for Lee on the first day as well.
"Lee also had a rough go in one-on-one passing," according to Pelissero. "He lost three of five matchups, with his only 'wins' a drop and a tackle that somehow didn't get flagged."
Like Breno Giacomini, we're willing to overlook the first day of practice that wasn't exactly sharp all around. And rookies are expected to struggle to some extent. We're just hoping by the third and fourth weeks of training camp, the mental errors are diminishing.
