SANTA CLARA, Calif. -- Prior to the San Francisco 49ers' first mandatory minicamp practice, offensive coordinator Greg Roman said he was looking for sharp workouts.The 49ers didn't exactly deliver.There were plenty of drops in a mostly mundane workout. However, I wouldn't exactly say it's cause for alarm. It's June and a lot of players were held out or limited. This is not high-intensity times.It's a time to continue to work on rhythm before the team takes a month break before starting training camp.
