I've been wanting to see the back of Cleary for a good couple of years now, however, I think he's be a good signing for Penrith - initially.
When he came to the Warriors we were a bit of a mess, the club culture was stuffed, we'd just gone through a salary cap rort, and things weren't looking good. He did a fantastic job of bringing stability and rebuilding the club from the ground up. I imagine this is what Gould wants him for as much as anything. He's a very calm person, and will bring consistency and stability to the Panthers team and organisation.
Having said that, I do believe his ability as a couch is limited. He'll do a great job for 2-3 years of rebuilding the club and making you guys consistently competitive, but I think there's a limit to how far he can take a team.
A very good coach, perfect man for a crisis, not convinced he's a premiership winner.
