It's not even "coach speak". I've been listening to him since he was named head coach. Just about EVERY INTERVIEW has him using the phrase: "I think..." In this instance, after having promoted Jim Caldwell to the position of OC, and with all the spotlights shining brighter than ever, Harbaugh, in talking about the new offense, says:
"I think it'll have Jim's imprint on it".
REALLY, John?!!! You think the new offense will have Jim's imprint on it? Wow. You are a great NFL head coach, man. SO decisive. SUCH a strong leader. Wow. Just wow.
On a more interesting note...
listen to Ray Rice's comment about Jim Caldwell having the respect of the guys in the locker room. And read between the lines. He's clearly suggesting that Cameron did NOT have the respect of the guys in the locker room. At least that's the way I'm reading it. (Also, Ray's bias towards wanting to keep the emphasis on the running game is obvious as well, rightly, or wrongly.)
