Top pick Tyson Jackson realizes the NFL is tough.
My take: It is going to get a lot tougher, Tyson. You just finished a rookie minicamp. Wait until training camp and the regular season. You better be prepared, though, Mr. Jackson. The Chiefs took you with the No. 3 overall pick and expect you to make an immediate impact at defensive end.
The Raiders have signed receiver Sami Parker after he tried out during last weekend's minicamp.
My take: Parker is a journeyman and he will have to fight to make the roster. But Oakland needs all the help it can get at receiver.
San Diego's special teams feel prepared for a rule change.
My take: There was a rule change that limits wedge formations on kickoffs. As San Diego special teams coach Steve Crosby explains, the Chargers weren't much of a wedge team anyway, so it shouldn't be a big problem. San Diego has been one of the better special teams units in the league and I expect it to continue.
