Build the Saints' 3-4 Defense

Can you explain why Bresee playing 3tech in a 3-4 between a 5tech and a 1tech is harder than him playing 3 tech in a 4-3 between a 5tech and a 1tech?
He makes tackles on run plays on avg 3-4 deep up field.

He will get demolished in a 3-4 system. I'm talking abused.

His strengths are 4-3 in the NFL and then it's a toss up.

1st round draft pick can't even start smh
