• The Cowboys traded overmatched corner Anthony Henry to the Lions Saturday in exchange for quarterback Jon Kitna. Kitna will serve as Tony Romo's backup, replacing Brad Johnson, who was an unmitigated disaster when he had to play for an injured Romo in 2008. Kitna, of course, was a fantasy darling for a couple of seasons while Mike Martz was weaving his particular brand of insanity in the Motor City, throwing for more than 4,000 yards in consecutive seasons. It all came to a sudden halt in a Martz-less '08, however, as Kitna played in just four games because of back trouble. And really, even when he was in there, it was clear: His impressive numbers were more about Martz and less about Kitna. If Romo gets hurt again in '09, Kitna would probably put up some acceptable numbers, though I definitely wouldn't go so far as to say he's a must-handcuff guy for Romo's fantasy owners. • Bryant Johnson, who played in Martz's now-defunct system in San Francisco, has moved on to the Lions, having signed a three-year deal with Detroit which presumably includes not all that much guaranteed money, considering Johnson's coming off a 45-catch, 546-yard season. Mediocrity is what Johnson has produced throughout his six-year career (the first five years of which he spent as third fiddle in Arizona), and mediocrity is almost certainly what the former first-rounder will provide opposite Calvin Johnson in Detroit. That goes double if Daunte Culpepper really is going to line up under center for the Lions. Plus, it's not definite that the Lions are done signing wideouts. Johnson makes a poor No. 2 NFL receiver, and (as I contended last fall) doesn't belong near your fantasy squad. • Last year, the 49ers did boast a couple of young and interesting receivers: Josh Morgan and Jason Hill. On Saturday, they added to that stable, signing Brandon Jones, formerly of the Titans, to a five-year contract with a surprising $5.4 million in guaranteed money. Jones, who'll be 27 in October, caught a career-high 41 passes for a career-high 449 yards last season, which isn't really very impressive at all. However, the Niners sure are paying Jones like he's going to be one of their starting receivers. GM Scot McCloughan puts Isaac Bruce's chances of returning at 50-50, so there's even a chance that suddenly Jones is a No. 1 receiver in the NFL. He's still got nice speed despite a bad knee injury he suffered a couple of years ago, and he has fine ball skills, but clearly has never set himself apart. Frankly, I still prefer Morgan. And in what figures to be a run-heavy offense, you probably shouldn't get all that excited about any of these guys. • The Broncos continue to remake their roster: On Saturday, they added ex-Eagle Brian Dawkins to their defense, to go with safety Renaldo Hill, whom they inked away from Miami on Friday, and defensive end Darrell Reid, whom they signed from the Colts. (The team was also reportedly close to signing ex-Browns linebacker Andra Davis.) What's most interesting here is that Mike Nolan is in charge of Josh McDaniels' defense in Denver now, and that new brain trust seems to believe the secondary was this defense's biggest problem in '08. Dawkins will play strong safety, Hill will be the free safety, and Champ Bailey will be at one corner (Dre' Bly was waived from the other starting corner spot). In addition, Reid is an interesting prospect who probably would've gotten more run in Indy, except he's been arrested twice. Denver will join the growing list of teams who'll employ a 3-4 defense this season, probably converting at least one of their edge rushers to outside linebacker. What they really need to be fantasy-relevant again, though, is a true two-gap stud in the middle, something the departed Dewayne Robertson obviously was not. If Denver can find that guy, they could be an important defense in fantasy again as soon as this season.
