Actually DI has the right take on this. Given what's available at this time Cole is a good signing. And while he was never a great pass defender, he had his moments, and is a good special teamer. Don't underestimate that role. We don't know what Special teams roles Harris played for the Donkeys.
Also compared to what Branch might have had to offer, Cole's knowledge of the Pats D might actually be of some limited use. For example who's healthy or not. plus calls and signals the Pats use to communicate. etc
In the end, they got a decent special teamer, a decent #6 CB, and possibly some info that might help. Sounds like a win to me.....and anyone else with half a brain. It was a solid depth transaction that is very unlikely to have any effect on the results of the game.
BTW- don't forget that "minor transactions don't always turn out that way. According to Rotoworld, when the Pats signed him, they labeled him a likely game day inactive. When we signed Siliga they described him as a depth move caused by all the injuries. Where would we be without those 2 guys now
