Adalius Thomas was one of the most sought after free agents several years back and was recently dumped by the Patriots. It sure seemed as though he was dropped due to his permanent resident status in Belicheat's doghouse. Much has been made of Thomas' inability to make it to a team meeting on time, never mind that the meeting took place in the midst of a blizzard. Belicheat knows a thing or two about linebackers so it seems probable that Thomas wasn't living up to expectations on the field either.
Regardless, Thomas might represent a real upgrade in Buffalo. Consider for a moment that Chris Kelsay is slated to start at outside linebacker if Schobel retires. (The sound you heard was Kurupt's head banging on a keyboard somewhere.) What if, however, the Bills traded Kelsay for a late round pick and a sack of onions and filled his roster spot with Thomas. Buffalo suddenly goes from starting a limited athlete with no linebacking (can that be a verb?) experience to a starting linebacker who was at least once a prime example of linebacking excellence.
Okay, the second part should be relatively straightforward. If Thomas isn't signed Buffalo can make the man an offer. As for the first part, a trading partner would need to be found. As (bad) luck would have it, the Jacksonville Jags suddenly find themselves short a DE. Buffalo wouldn't get much for Kelsay beyond the aforementioned bag of onions.
Unless, of course, Jacksonville kept the conversation going by inquiring about a certain running back to complement (read: back up) Maurice Jones-Drew.
