If I had to grade it right now...
OT Noteboom: C to B, somewhere in there. He has good feet for a big guy, but has to work on strength. He got taken where he did due to a crappy class, so whatevs. Was afraid Rams would push OT with that pick and they did. Should stick on roster and get every chance to be a guy for the future.
OL Allen: B. I like this pick more than Noteboom in round 3 personally. Think this guy will stick and give us depth this year.
DE Franklin-Myers: C range. He's a 5T most likely in our defense, and I think his drafting is in response to what our line played like after Brock went out in the playoffs.
ILB Kiser: C. He's a two down LB in this defense IMO. Hope I'm wrong.
OLB Okorongkwo. A. Getting him where they did was great value and he's a huge need. Long arms, good range, and just great fit for this defense. Will probably start and not leave the field for us.
RB Kelly. A. Watch Tennessee's games and it's Kelly and a bunch of JAGs. Great pickup in round 6 man.
OL Demby. ???. Haven't seen enough of his stuff to really comment. I do trust our OL coaches though.
DT Joseph: B. He's a big kid who can move, flashed a little, just what you want if you go DT this late.
DE Young: C. Medical concern and whatnot but this is round 6 so whatevs. Big and athletic, we'll see.
LB Howard: A. Solid late pick, undersized but watch TCU's defense he's got good range and gets after it. Really like this pick so late as it is.
DE Lawler: ???. Didn't watch any of his tape, but it's round seven so yeah.
Wouldn't even try to grade the whole draft right now other than to say in comparison to the quality of guys some other teams added the Rams came up a bit short. Positive is that we added veterans who we will hopefully sign.
Going into the draft we knew we needed some LBs across the board and OL depth. So judging from that perspective and given that we didn't have a round 1 or 2 pick, I think Les did pretty damn well.
At this point I'll also bet the Rams are hyper-aggressive on LBs in the UDFA period here. So strap in for more additions IMO.
