Your first statement is a bit overzealous...sure, its fact, but that is by proxy of sheer volume. There is usually over 300 "3-star" kids every year...roughly 50 "5-stars" and 150 "4-stars". Give or take a few depending on the service and how they rate players. 5 and 4 star players hit at a higher percentage and trend to play at a higher level than the 3* in any given year.
Sumlin's teams haven't exactly produced NFL talent on the OL...he walked into TAMU with the two best tackles in the country...but, I do agree with what you are getting at...he's not being recruited like a scrub. He's got legit interest/offers. As Mike Bakas would say...he's being recruited like a three star.
With that said, and not pertaining to your post...I think we are all aware that the kid is developmental...Kehoe obviously feels confident in the kid as he's been after him for two years. I like what I've seen from him in regards to growth...glad to see he was able to do that on his "own time" at prep...so he's coming in with a full clock and already grew a ton during that year. That's basically a saved year of development.
It's not really overzealous when you view it in light of the fact that there are only 32 NFL teams compared to the reams of college programs out there and all the kids who get recruited every year.
You'd think that the 4 and 5 star DL and OL would rise to the top and take those limited jobs on those 32 teams, but they don't.
As as Sumlin goes, he's proven that he's a very good offensive mind. For those feeling any trepidation over Sunny's offers they should be assuaged by Sumlin feeling good about him.
But, they do.
Just an example or two because I'm not going to do an analysis over a decade or anything...
2007...Scout had 9 5* offensive linemen...5 offensive linemen are now playing in the NFL and one will be a 2013 draft prospect.
2006...Scout had 10 5* offensive linemen...6 of which are now playing in the NFL.
Conversely, there are 200+ 3* offensive linemen in any given year...10-20 may make the NFL. Maybe you'll find an outlying figure on a crazy year.
Yeah, sure...there are more 3*, but 5*'s have an insanely higher on base percentage.
