I have drafted Palmer in every league I'm in this year... I have great faith in this kid. Never mind that he was a #1 overall... in fact, you can even assume he sucks (I don't, but follow me on this). His supporting cast alone makes him a top 10 QB. One could say Joey Harrington has quite the cast too without doing well, but Carson has something Joey doesn't... a killer o-line, which if you don't think that makes or breaks anyone, I say this... a solid o-line is without a doubt the most important thing a team can have to succeed. Mediocre personnel can preform well with a strong front 5.
now, you can get into the other equations... USC QB, 1st overall, 1300 rusher to accompany him, 3 great big play receivers, improving defensive support, continued improving play... especially in a dynasty league, grab this guy. And as already said, worth a starting role in a 12-teamer... maybe 8 teamer. Could produce top-6 numbers... (though I predict more in the 8-10 range).
'Cause I'm Cow ... Boy ... for life.
