Lovie Smith has said it time and time again. Jerry Angelo has repeated it for years.
You can't have too many defensive linemen.
Perhaps to that end, the Bears were represented today at Georgia Tech's pro day. The Yellow Jackets have defensive end Michael Johnson, one of the better prospects in the draft. Johnson has a rare combination of size at 6-7, 266 pounds, and athletic ability. He was timed in the 40-yard dash at 4.68 seconds at the combine. He's got the long arms and quickness to come off the edge and create instant problems for the offense.
Some have questioned his consistency, or rather his lack of it. That's something he's going to have to answer with NFL teams. There was a pretty good pass rusher at Florida in 2002 who had similar questions. Alex Brown turned out pretty good for the Bears and, if anything, he's been a model of consistency. Johnson isn't expected to last until the fourth round like Brown did.
But recall what Angelo said about finding an elite pass rusher with the 18th pick in the draft--if the player is still on the board at 18, he might have some traits you love, but he's not elite. There are some holes there.
