Sad news that Ticat safety Dylan Barker is retiring due to back injuries. Barker didn't play at all last year, so in a sense the Cats don't have a huge hole this year. He was a non-import starter on defence, who the Cats replaced in 2011 with an import, which did cause ratio problems last year (i.e. Stevie Baggs not playing in the Montreal playoff game).
Perhaps the Cats now look to draft a safety in June, although I'm not sure what's available and how high a pick the Cats would use. Barker was the first overall pick in the 2008 draft, so this is certainly not great for the Cats.
