I'm sorry, but the Lee to Hoffpauir downgrade is MASSIVE.
http://www.baseball-reference.com/h/hoffpmi01.shtml28 years old before playing a game in the majors
MiLB career: 96 HR in 675 games (about 23/162), .290 AVG, .832 OPS, 425/211 K/BB ratio
Majors: (in 33 games) 2 HR in 73 AB, .342 AVG, .934 OPS, 24/6 K/BB ratio
He's like the Nick Stavinoha of the Cubs. He has one good minor league season and suddenly people are putting him in as a major league level starter. Bullwhacky. If the Cubs trade away Lee they better get solid pitching prospects and also sign Teixeira.
Also, I don't see the big need for Peavy. The Cubs went out and got another ace over the summer. Why do we need a third ace all of a sudden? Most teams would love to have a Zambrano/Harden/Dempster/Lilly/Marshall rotation. Should Dempster sign with someone else, I wouldn't mind seeing Lowe in that three-spot. Failing that,I wouldn't mind seeing Maddux or Moyer return.
