Seth has a nice breakdown of Gay's snaps on his blog. Consensus basically was he looked good vs run, still learning to play in coverage. Which is why they're easing him in.
Here's some gifs yo.
Really nice fill here. Aggressive.
Great fill. Makes the tackle miss completely, then gets back in his gap and cleans it up with Pennel.
Seth said in coverage snaps they mostly asked him to either cover the RB or rush the passer if the RB stayed in to block. Here you can see it's a tough read on the RB considering his movement towards the line but when the RB commits to the block, Gay is a bit slow to pick it up and start his rush. When he does commit to rushing you can see the speed take over. Once he learns to trust his eyes, plays like that can turn into sacks. He still gets credit for the pressure here.
Bad coverage snap that didn't end up mattering but you can see Gay get suckered by the fake and then gets turned around trying to drop back into his zone. Eyes in front young man. Head on a swivel. Get that backpedal going.
Gets washed out by the OT, no attempt to shed. He'll learn.
All in all, 25 snaps is a good start and was an overall positive outing. Expect him to stay at SAM the next 4 games at least, maybe the whole season, barring an injury. All his snaps were in base looks, meaning zero nickel or dime snaps. Spags clearly thinks he's a work in progress on obvious coverage snaps but is starting to trust him when it’s not a passing down.
If you think he should be starting already I would say you should have watched his college games. You may say I don't like projects in the 2nd round. That's fine too and fair criticism of Veach, but water under the bridge at this point.
All i can say is I really feel that if this kid puts it all together he could be really special. We'll see soon what kind of worker he is, because the tools are all there. Amazing athleticism along with a lot of aggression can take you far (some of his run fits were violently aggressive). We haven't seen that in the LB corp for quite a while.
Trigger alert, it may be next year before he really starts to put it all together, but he will flash like hell at some points this year.
