"When his technique catches up with his work ethic, then you're going to really have somebody special."
Well, Bill Kollar already ranked as a huge guy for the 2009 Texans, who as a team had just 25 sacks a year ago, 12 of them from Mario Williams.
The team's new defensive coordinator is expected to keep Williams' career on the rise, to squeeze maximum production out of free agent addition Antonio Smith who will play end and tackle, to get Amobi Okoye back on track after a high ankle sprain slowed him in Year 2 and to up the production of the rest of the group.
Now, too, he'll be expected to show Barwin how technique can turn that excellent work ethic into NFL production.
I talked to Kollar for a recent blog column, which you can find here is you missed it or care to revisit.
