OK, so here is a bit of irony that I just discovered:
When Leftwich signed his FA contract with the Bucs, the Steelers were awarded a compensatory pick in the 7th round of this year's draft: #242 overall. This was not TBs own 7th round pick. They still have that at position #217.
So, now, the Steelers come back to the Bucs and say, we will give you the #242 pick that we got for losing Leftwich to you to give him back to us. Tampa says no, we want your regular 7th round pick, #225 for Leftwich. The Steelers give in and agree to it.
So, basically the Bucs gave up nothing for him, get a year's use out of him. The Steelers get an older, wearier Leftwich and give up their #225 pick.
Tampa now has their own #217 and the #225 pick for a guy they may have released in training camp!
