Three receivers (WR and TE) in the first four picks seems highly unlikely.
So far, all of Gute's first round picks have been at the most valuable positions, QB, CB, Edge, OT, S and TE... he hasn't gone OT or TE yet, but it would be surprising to see with him go two outside of these positions in the first unless it's two WRs.
Also, so far, Gute has never selected a DT about #150, so suddenly in the top 30 would be a surprise.
Olave is a speed WR with good route running, though some have suggested he was the clear #3 WR at Ohio State and on the smaller side when Gute has only drafted larger WRs so far.
NT Jones is a bit like Clark is that normally NTs are two down guys but they basically never came off the field even in today's age of football that often rotate their DTs when they can to keep them fresh, they stayed out their for entire games and hustled. Their endurance potential could be mega pluses. That being said, 1st round seems a big high consider he didn't face the best OL at UConn, but I believe he did do well at the Senior Bowl.
WR Pickens is a large athletic WR that showed off early in his career and then got injured and basically missed a bunch of time finally getting healthy for Georgia's playoff run last year. A bit of a projection where he might go, but he's big and athletic with great body control.
TE McBride was on a horrible offense, where he basically was the passing game, putting up unbelievable stats for a TE as the offense schemed to get him open and the defense schemed to stop him and the running game, and he still produced huge numbers. Extremely well rounded TE, of he was a great athlete, he'd probably be a first rounder, but he's not a bad athlete, I actually think mocks will be surprised when he's taken in the top 45.
Edge Wright, I don't know.
OT Diesch, had one of the best pass blocking grades last year in the Pac 12, though Pac 12 isn't known for their pass rushers lately either. But he's done well with what was put against him.
S O'Neal, I don't know enough, but the Packers do need Safeties.
OT Tom, honestly the best comparison I've seen for Zach Tom is David Bakhtiari. Everyone is saying their two small (they're basically the same exact size) to stay at OT in the pros despite their absolutely amazing but finesse pass protection skills and ability to mirror defenders. Everyone is saying they should be interior guys, but I think they might be too finesse for run blocking at OG. The biggest difference, is people were projecting Bakhtiari's best position to be Center, despite he's never played it, where Tom was a Center his first years I'm college before switching to LT the last two years. But the bottom line is, if you can teach Tom to stop the bull rush/power game, then like Bakhtiari he can be one hell of a freaking pass blocker in the NFL, but due to their finesse styles that's not a given and neither is their run blocking. So they can either be an elite pass blocker, or a bust, and not much in between. I say go for it, and have him follow Bakhtiari with everything.
The rest of the picks I don't know so well, though I believe CB Flott would be going a lot higher than the end of the draft if he weighted in at more than 175 lbs, and some believe he only weighted that much because he was trying to gain weight for the combine and he was possibly played 10 to 15 lbs lighter, despite being over 6' ...
Don't get me wrong, he plays and fights hard, and technique matters more than size, but size absolutely does factor into it when you start talking about more than 20 lb difference. Especially if that's 20 lbs of muscle, and that's assuming he can avoid all the players over 200 lbs, which would be even more. If some team can over look his weight (which I'm sure some team will, he'll go higher than the 7th round) though the Packers do seem to have size limits and I'm guessing he'll be off the Packers draft board as not being heavy enough.
