Forget Lee. Forget Soriano.
Spend the cash on Schmidt and Zito and do the rest with trades (not for world beaters on offense). Re-sign Huff to play 3B. Re-sign Andy.
The Tigers are about to be the second team in a row to prove that you win championships with a great pitching staff and a team of great role players. You need one big time slugger and someone behind him who can be expected to drive in some of the runs that the slugger doesn't deliver. You need an above average leadoff guy and someone who can move him over.
I'll take my chances with Willy, <2 guy>, Lance, Huff, Luke, Biggio, Adam, Brad, Pitcher and a staff of Roy, Zito, Andy, Schmidt, anyone (me?). We'd need a RF, but not a Lee-type offensive player.
You'd be spending Clemens' money on Zito and Bagwell's money on Schmidt with some left over for the raises due.
Wheeler closer. Trade Lidge, Ensberg, and Lane for decent, "cheap" role players.
Pitching. Not hitting.
