I'm glad they're giving him a workout. If he's better than Thigpen, which he probably is, then sign him...if we're sure there won't be any QB controversy drama.
He has a history of controversy, as well as a questionable work ethic, and I never want to see any episode ala Johnson-Flutie. The Bills, to me, are a stable team of likable guys. I worry that Young could be a harbinger of said drama but I'm also willing to keep an open mind.
And just to temper some of the posts I've seen here, and especially elsewhere about him unseating Fitz and even winning us a SB (just saw that one), the guy was cut...
for Trent Edwards.
