Before I laugh, what do you mean by "star" player?
I think Janis can be a very good special teams player and who knows, maybe a pro bowl special teams player. I guess that is possible. So if that's what you mean, I can possibly agree.
But no way at all is Janis a pro bowl "Star" WR.
It's bizarre that you're blaming Green Bay for Janis's inability to develop. Janis is the perfect example of a player with a lot of ability and a 10 cent brain. He has decent hands and fast as lightning. But Janis still a few years later has not learned the playbook. He still can't run proper routes and still has no idea where to line up or where to make his breaks. That is not the Packers fault, it's Janis not being able to grasp it. Look at all the other receivers, they seem to get it just fine. Packers WR's not knowing the system is not common practice, it's not been a problem. But for Janis, he just doesn't get it. I wish he did though, that would make the team deeper.
