will never be concerned about Charlie Weis at KU. He will get a few players though most of these kids are of the 5th year transfer variety. McCay was being moved to defense if he didn't transfer from OU.
1) Weis will not pull a lot of 4 star kids straight from high school. (I realize KSU will not either but Snyds has never had to in order to be successful)
2) Weis is one of the worst in terms of development. Everything is great if he's got a lot of players with skill and already developed (it's called the NFL)...it's quite another to develop players from the moment they leave their high schools to the college game. He failed miserably doing this at Notre Dame. He inherited a veteran group his first two years there...it went downhill from there.
What Charlie is....
A fantastic offensive coordinator and great mind for that side of the ball.
What Charlie is not...
a great college coach. He's outstanding at working with coordinating a lot of finished products...not so much if he has to develop those products.
What makes Snyder so unique is the culture he develops within a program and the development he achieves.
Weis doesn't have to be good at development. He's got guys like Tim Grunhard and Clint Bowen, who are both excellent at player development. His entire coaching staff is different than it was at Notre Dame outside of a few coaches who he brought back for recruiting purposes. I don't know if Weis will be successful or not, but I do know that he'll give a better chance than Turner Gill did.
Pretty low bar there Beems
I don't think you guys would be complaining too much if K-State's next coach came in and signed three 5-stars right off the bat and added another US Army All-American at linebacker.

the Notre Dame QB lost his starting job and has one year left. The LB never started and has one year left. The BYU QB lost his starting job and it was one of the worst offenses BYU's had in memory. McCay was a disappointment as a receiver. KSU wasn't interested in him as a receiver either. The kid you got from Nebraska was a disappointment this past year. I watched him specifically in their game vs. Ohio State...he was the invisible DL.
These are transfers. Weis will not be signing a bunch of 4 star-plus kids out of high school. He might get a few recycled names but he's not recruiting to Notre Dame.
I'm not sure why you pegged Grunhard as a great developer of players. He had better talent than most teams he faced while a high school coach...how, again, does that suggest anything at the college level?
There is a dramatic difference between coaching in high school and the NFL vs. the college game. Weis has been a massive failure in the college game both as a head coach at Notre Dame and a coordinator at Florida. These are the facts and, before long, you will no longer be able to ignore them.
