Where did anything about the team's record? It doesn't take a seer to realize that the Browns are an improving team.
First of all, there is a difference between "improving" and "good". New HC's aren't generally given more than 3 years to get a team from bad to good. Secondly, you simply cannot say after 5 games that the Browns are improving so yes, it does take a "seer".
There are 4 classes (with some 5th year exceptions) on a college team. When Weis arrived, he had only Ty's players available. Those players move from freshman to senior and then graduate. A coach is stuck with the previous coach's players for 4 seasons, barring early exits. Ty's players are still on the Notre Dame team, and are the players who should be the team's best. The players are just bad, as the recruiting 'analysts' predicted they would be. Now, once Ty's players are gone, Weis will be reliant upon his own recruits and will stand or fall based upon their success. That time simply has not yet come. Weis proved quite capable of coaching talent when Quinn and company were around. The question is going to be whether or not he can recruit and develop talent as well.

Notice the year for that first class.
I didn't read your link, but when Charlie arrived he had a higher percentage of guys inherited from the previous regimes. Now, he has 2 or 3 classes of his own recruits, with those guys replacing the incumbants. So if his team is getting worse (and it certainly is worse by record than it was in his first two years) it must be because his guys aren't as good as the guys he inherited. Recruiting is a huge part of the job of a college football head coach - and it does not appear that Charlie is very good at it.
As for Mangini, I was not defending him, just explaining his position. He was a success last year, and has not been one through 5 games this season. As young as he is, that doesn't make him a failure. He showed last season that he can coach at the NFL level. Now he has to show that he can learn from his mistakes and improve.
