Is it safe to say Martin Mayhew is the worst GM in the league when it comes to drafting?

2009:
1st. Matthew Stafford, QB
1st: Brandon Pettigrew, TE
2nd: Louis Delmas, S
3rd: Deandre Levy, LB
3rd: Derrick Williams, WR (LOLOLOL)
4th: Sammie Lee Hill, DT
6th: Aaron Brown, RB
7th: Zack Follet, TE (Started the "china doll" nickname for Stafford, broke his neck as karma)

2010:
1. Ndamukong Suh, DT
1. Jahvid Best, RB (Injury proned, career over)
3. Amari Spievey, S
4. Jason Fox, OT (Has yet to play a game)
7. Willie Young, DE

2011:
1. Nick Fairley, DT (2 arrests)
2. Titus Young, WR (3 team suspensions, then cut)
3. Mikel Leshoure, RB (2 arrests, 2 games suspended, torn Achilles )
5. Doug Hogue, LB (Cut after one year)
7. Johnny Culbreth, OG (One arrest, then cut)

This bum needs to GO.

BQ: What would you say his best pick was after round 3?
@K-Dawg: Yea that's what I meant. But I'd use the term "Linebacker" loosely with him.

And yes K-Dawg I can blame the GM for injuries. When the guy has a history of injuries...don't draft him. Simple as that.
