Can't remember the last time such a major signing came so out of the blue. I rate him but it does strike me as a bit of a weird addition given Gus has gone on record about how important it is to have balance in your cap and invest more in the spine.
Also, put me in the 'strategic leak' camp (if one exists). Wouldn't surprise me at all if the club knowingly leaked the photo just before the Panthers big celebration. I'm sure there's still some bad blood there after the whole Burton thing and Gus as much as he's a smart operator, has an ego the size of king kong. So he'd want this pick up out there asap for any other potential recruits that might be on the fence. That's my theory anyway.
