OK this might be from left field but....
I think McIntosh was resigned in order to fill a spot temporarily and then to trade. Someone will need him once a linebacker goes down....
I mean he's not good in our 3-4 defense, he sat out there on the FA market, why not sign him as depth for a little while and trade him to somebody for a 6-7th when someone goes down?
So to answer the question yes, I think Alexander makes squad and contributes in the end. How can you root against a guy like that?
edit: Oh yeah and McIntosh let that TD run happen 2 nite.. Jus' sayin.
