I am not, at all. They weren't really highly rated recruits and then they didn't play at all for an entire year. We would be in an absolute uproar if we took a transfer who was a 3 star recruit, played like 70 minutes, and has to sit out a year. Even if you liked the kid as a recruit, you already lost a year of development AND he can't play for another year. I'm not surprised in the slightest they couldn't get any decent offers as transfers. Plus, those are the 2016 recruits, which are best case scenario. Imagine how much it would be for Wilson, who played less last year than his FR year. I'm not sure how much was on him and how much was on Stallings, but no one would take that transfer.
Don't get me wrong, I am not saying I think any of those players were destined to be really good, but I am not surprised at all they had no real transfer options. Any coaches would be insane to take them.
Hell, look at Ellison for us and compare. He was a decent rotation player/almost starter (albeit on a terrible team and was about to be pushed way down the bench) who had produced a good bit for two years and his options were few and far between. Geno Thorpe was even worse. To be a successful transfer you have to really be proven you can be a high level contributor right away or have enormous upside.
