Wouldn't it be a better argument if the players you examined actually won or at least went to a Super Bowl?
NE- Brady, 6th round, drafted by NE
CAR- Delhomme, Undrafted FA, signed by NO
TB- B. Johnson, 9th round, drafted by MIN
Oak- Gannon, 4th round, drafted by NE
STL- Warner, undrafted FA, signed by STL
BAL- Dilfer, 1st round, drafted by TB
NYG- Collins, 1st round, drafted by CAR
TEN- McNair, 1st round, drafted by TEN
DEN- Elway, 1st round, drafted by BAL(Indy)
ATL- Chandler, 3rd round, drafted by INDY
GB- Favre, 2nd round, drafted by ATL
NE- Bledsoe, 1st round, drafted by NE
In fact, only two out of the last eleven SB QBs were drafted in the first round by the team that they went to the SB with. One of those two player?......Drew Bledsoe.
In addition, two of the "clowns" that you listed have won Super Bowls unlike all but one of the QBs that you listed as proof that a first round QB playing for the team that drafted him is the recipe for success. And that one QB? .....sixth round draft pick.
