What?! One of the better 4-3 OLBs in the NFL is a 'meh' selection at #15? If coverage linebackers can be found anywhere, why haven't the Packers picked one up? Maybe you didn't read through what I wrote but I'll summarize. Irvin, at linebacker, has NO weaknesses in his game. He is good at rushing the passer, stopping the run and covering receivers and this was his FIRST year playing linebacker in the NFL.
I'm sorry, the burden of proof at this point is on those claiming BJ Raji is actually good at rushing the passer, despite not recording a single sack in over a year. I'm also curious why a coach would tell a player, "hey, don't rush the passer, just push the pocket. See, sacking the QB would be good but NOT sacking him is better". If the idea is that they don't want to open running lanes for the QB, well then I would point out that we didn't really play a ton of rushing QBs this year. Weeden (44 rushing yards), Stafford (69), Cutler (118), Dalton( (183), Flacco (131), Ponder (151), Manning (36), Ryan (55) and Romo (38) are not exactly a list of scary scrambling QBs.
