Jackson sharp during drill

After being criticized on the QB Watch by an unnamed colleague, Tarvaris Jackson sizzled in a six-on-seven drill inside the 15-yard line. I did not keep track of how many passes he threw with the second-string receivers, but Jackson was flawless and had at least four touchdowns, two of them to Martin Nance.

That is tempered by the fact that he didn't do that against the starters, who picked off Brooks Bollinger (Chad Greenway hauled in a tipped ball).

In other developments, rookie Aundrae Allison left the field, walking gingerly. Also, Chester Taylor and Ben Leber are among the players not at practice.

Bryant McKinnie, though, did take part in his first 2007 training camp practice.
