Lucky, thanks for the welcome.
Here are some thoughts based on what you expressed in your reply:
Though there's only one football, the presence of Mike Williams will help make those around him better. Someone(s) is going to be in a favorable coverage situation and/ or Kevin Jones/ Artose Pinner, and Shawn Bryson are going to have bigger holes to run through.
For what it's worth, the Lions haven't been to the playoffs for 5 straight seasons, as the team made the playoffs in the 1999 season. Barring the injury factor, I'm confident the Lions will return to the playoffs this coming season.
Regarding the players on Defense you suggested as alternatives, only Derrick Johnson would have likely seen the field on a regular basis. Unless the Lions projected Thomas Davis as a OLB. With the FA addition of SS Kenoy Kennedy, Davis would not have filled a need. As for Demarcus Ware, he probably would have only been a situation pass rusher in the Lions 4-3 scheme. Ware would have been a better fit for the Texans, if he would have remained on the board when they were on the clock. Hence, if you base playing time for this season as a major criteria on who to select ( I think it's a secondary criteria, compared to the bigger picture) as you are suggesting, Davis and Ware would not have been better alternatives than Mike Williams. Personally, I think Derrick Johnson or Shawne Merriman will turn out to be the best Defensive players in this draft. Providing a long holdout doesn't derail Merriman's career. However, it's clear that the Lions rated Mike Williams significantly higher than both of them. Going into the draft, I would have been very comfortable with Mike Williams, Derrick Johnson, or Shawne Merriman at # 10 but have great respect for the Lions BAP approach.
Matt Millen was a horrific GM ( CEO) in many ways, his first 2 years in the league. Since the winter of 2003, Millen has developed into one of the better GM types in the league. With all due respect ( those who know me know I don't talk trash), if I was in your position as a Texans fan, I would be seriously concerned about Charlie Casserly as a GM. IMO, the this off-season has set the Texans back noticeably. Travis Johnson doesn't appear to be a good fit in a 3-4 two gap scheme and the price in acquiring Philip Buchanan was very high. The moves at LB are also questionable. Time will tell of course. Though I gladly admit the Jaguars are the team I hope wins the AFC South each year, I have nothing against the Texans franchise. ( I'm certainly rooting for Reggie Swinton to do well. ) The only team in the division I truly dislike is the titans.
Though Matt Millen badly missed on FA WR's in the past, the addition of Kevin Johnson this year should pay dividends.
A major part of the value of the Mike Williams pick is the Lions Offense should stay on the field longer and help give the team leads in the 2nd half. As a result, the Defense should be fresher and in general be more effective playing with a lead. The Lions Defense was actually the team's better of the two units in the last couple of seasons but the lack of Offense much of the time diminished their effectiveness. Injuries didn't help either. Not having OLB Boss Bailey for one down in 2004 was a huge setback. Having said all of this, there's no question that the Lions need more of a consistent pass rush off the edge. This despite the fact that DE James Hall had 11 1/2 sacks in 2004. He's a good all around DE but not a differential pass rusher. In the end though, the decision on draft day came down to the fact that Mike Williams was the highest rated player, who can provide plenty of value at the same time. One thing that is very important to emphasize is when you reach for players, that almost inevitably leads to salary cap problems down the road.
I'll save my comments about Joey Harrington for another reply, if this thread continues. One additional thought for now: Don't count out Charles Rogers.
