My thoughts:
C. Coleman- Seemed to show a lot in training camp. Even the normal negative media members were giving him praise. Looked good in the beginning of the season. No doubt the injury (missed like 6 weeks) and musical chairs with QB has hindered development. Needs to improve hands and put on some pounds though. Doesn't look much bigger than Hawk. Need to see more and I expect to see more next year.
E. Ogbah - Probably the most impressive of the class. Top 20 overall rookie? I didn't notice him much when he was playing LB (although he was graded well by PFF), but he seems more productive at DE.
C. Nassib- Nassib looked good in the preseason and early in the year as well. Same situation as Coleman though. Broken hand has set him back and he needs to add some weight.
S. Coleman - Don't really have much to say. He hasn't been active more than 1 game this season and might not have gotten on the field at all as far as I know. Some say its a "redshirt" year which I don't really get. Coleman is supposed to be good and even if Pasztor is playing better now, he wasn't playing great in the beginning of the season.
C. Kessler - Prob the most surprising pick of the draft. Most say overdrafted. Looked horrible during preseason IMO, but came in and looks like at worst, a solid backup. Some think he could be the guy. I lean towards no, but we haven't seen him attempt to open up the offense which makes it hard to judge. Has statistically put up equal or better stats than Goff and Wentz I believe. He was right there with Wentz and Dak earlier in the season.
J. Schobert - Meh. Can't see him being anymore than the special teams player. Had a decent amount of time at LB in the season. Think he even started a few games, but seemed largely unproductive.
S. DeValve - I like DeValve. Has gotten more run later in the season and seems to get open and catch the ball when it is thrown to him. I'd imagine he needs to put on a little weight and improve run blocking if he wants to be Barndige's heir opponent (which may be needed soon).
R. Louis - Draft analysis seems spot on with him. Great athlete that can't catch. Had a lot more opportunity earlier in the year at WR, but couldn't catch the ball consistently. I always notice him on special teams so that seems like a plus. Could be a pretty good player IMO if he could catch. He got open a lot when he had the opportunity.
D. Kindred - Showed some flashes, but was a little inconsistent. Believe he is on IR now. Being a starter is still a possibility in the future IMO.
J. Payton - Does nothing for me. By far most disappointing rookie WR. Heard nothing in camp/pre season/reg season. Inactive most weeks. Was also suspended for drugs. I don't see him making the 53 man next season and just wish the Browns would cut bait now actually.
S. Drango - He is normal starter at LG now with injuries. Has had some bad plays but seems like at depth guy at worst.
R. Higgins - Hollywood seems entrenched at the #4 wideout right now. Pretty unproductive, but catches the ball when it is thrown to him. May be the athleticism knock on him, or it may be because he is the #4 WR. Still worth developing IMO.
T. Caldwell - I think he was active for the first time last week. Wouldn't expect him to be on the team next season.
S Wright III - Gone. Cardinals claimed him off of practice squad last week.
