Who do you NOT want the Saints to select with their 1st round pick?

If he's available at 28 we'd be idiots not to take him
Personally I'd like to know how Payton feels on this topic. Mac seems to be fairly similar to Brees' play style... the question is, does Payton want to branch out and try something new at the QB position or does he want to stick to the formula? I'd prefer to keep Payton happy.
