QB Coleman ~ TON of VERY RAW potential. Has a lot of little things to work on, but a year or two of QB school and the Packers MIGHT have something very good if they're able to keep him that long.
RB Marc Tyler ~ I think he's a good receiver out of the back field but I just didn't see the spark or potential. Maybe if he loses some weight (like someone said he's trying to do) he might show more. (I kinda wanted Tauren Poole from the Panthers, who already have a good group of RBs, also Coleman and Poole played together before Coleman transferred)
WR Borel ~ Borel has a quick twitch just like Driver/Cobb, with a little time and space can make something happen. But needs to catch and hang on to the ball... also less east/west on punt returns (IMO).
TE Bostick ~ I didn't see the practices but I've read he had a pretty good camp as an UDFA WR trying to become an NFL TE.
OT Datko ~ He showed some potential, and could become an NFL OT.
OG Greg Van Roten ~ Sounded like he did well in the pass rush drill and improved well over his time. Not sure if he can play OT or C though.
OL Chris Scott ~ I'm a bit disappointed, Scott comes from the Steelers which I don't think has had the best OL or OTs. I thought Scott had some potential coming out in the draft best I guess he hasn't be able to get it out yet. But he's from the Tennessee Volunteers (so were Scott Wells and Chad Clifton (also I think QB Coleman played with Scott before Scott went pro/Coleman transferred)
DE Guy ~ Based on college video, I think he's got some potential, seemed to be able to get attack the play. But struggled with double teams and when they ran it right at him. I really didn't see much from him this preseason, which is disappointing because I thought he'd break out. I think he's better than other PS DL guys we've had in the past, but I don't know if he'll be able to break out or not.
