QB moves by Cleveland Browns: Really?

The past few days have been very exciting, Cleveland-Browns-wise. By which I mean, as usual, that Mangini has boggled my mind:

1) They cut one of their QBs, Derek Anderson.

2) They got Seneca Wallace from the Seattle Seahawks (I'm not blaming Mangini on this one since Wallace must have been Holmgren's idea. But still).

3) They acquire Jake Delhomme days after he was cut by the Carolina Panthers for sucking big-time last season.

4) They traded remaining QB Brady Quinn to the Broncos.

So their starting QB is now either the back-up for Matt Hasselbeck or Jake Delhomme, who was really not very good last year (to quote one Yahoo commentator, he was the 'worst QB not named Jamarcus Russell').

This is almost as good as when Mangini acquired Brett Favre, but not quite. Because at least you might deceive yourself into thinking Favre could be good. These guys? I am confused.

Last year's QB ratings:

Anderson: 42.1
Quinn: 62.7
Wallace: 81.9
Delhomme: 59.4

League average: 83.4

Not like they were all that phenomenal as QBs, but I mean, you've got four guys here under the QB average and you purposefully went out of your way to acquire two of them. Hence my confusion.
