Rob Gronkowski participated in 7-on-7 drills today, according to CSN's Tom Curran via Twitter. This is the first time Gronkowski has participated in group drills during training camp. Previously he'd been working on the sidlelines individually. Gronkowski is recovering from a combination ACL/MCL tear. He's unlikely to play this preseason, but hopes to be back for Week 1 of the regular season.
This is good progress for Gronkowski, but also a reminder of how far he still needs to progress to be ready for the season. He's being taken as the second TE overall right now, ahead of Broncos TE Julius Thomas. So owners are not factoring in the risk that Gronkowski misses time at the beginning of the season. Whenever he does return, he'll have gone about nine months without playing live football, so there may be some rust at first. When he's on the field, Gronkowski is a must-start. But if you plan on taking him, make sure to monitor his progress closely.
