I have done a bit of scouting myself, gave it up mind you due to other commitments.
I haven't seen enough of him to judge tbh, and I don't think it's fair to judge on the appearances he has been given, and will wait for more opportunity to see him.
Would also point out, you may have a background in scouting, but I'm pretty sure Mark Robins knows what a good striker looks like, and I think TW has enough experience scouting as well.
I also disagree on Stevenson, while he perhaps wasn't as good as some games last year, he along with Andreau, pushed the team up the field about 15 yards, and recycled the ball well, yes he didn't shoot perhaps when he could have like last year (although it could be argued this is actually a sign of greater maturity as it is likely it wouldn't have troubled the keeper) he didn't try any killer passes but he didn't have a lot of movement in front of him, and most of the time he had 10 Newport players in front of him.
His tackling was good when they attempted to break, and he played better than Kelly had in that first half.
