Coyle is NOT soft. He doesn't go for big blow up hits, but he's 23o lbs. of muscle that finishes checks, rubs out other players at will, and will take a hit to make a play, which is a very underrated ability. There is nowhere on the ice he won't go, and I've never seen him back down from anyone. He has his faults, but I occasionally hear about him being "soft", and wonder WTH people are talking about.
He doesn't fight, or when he does, it turns into a wrestling match. Other than that, he is a very physical player. Tough to play against. Just doesn't do the cheap stuff like elbows to the head and cross checks to the back. If that makes him soft, then...
I say this as a guy who has watched about 90% of his games as a pro.
