Offensive Coordinator Rich Scangarello seemed to agree with Fangio's assessment of the benefits of Lock's recovery period.

"For a guy to step back without the pressure and to observe, to work and grow as a player in this league, regardless of the position or the person, it only benefits them," Scangarello said. "I really believe that. He addressed it the right way, he attacked it the right way and in the long run we'll see how that pays off, but I think that, yeah, it definitely can help somebody if they approach it the right way."

Through two days of practice, Fangio has seen that translate to the field.

"I think he's looked a little bit better the first two days, albeit [in] eight to 10 snaps, half the scout-team snaps," Fangio said. "[It's a] very limited sample."

Outside linebacker Von Miller, though, has already seen enough to make up his mind about Lock's potential.

"I just want to be here when he gets famous," Miller said. "He's going to kill it. He's going to kill it. He's got everything you need. The other day, he ran out and did like a little bootleg [pass], and he threw it and it was an incomplete pass. But I've seen a lot of good ones play, and that was probably the best incomplete pass that I've seen thrown. He has a little flip up [in his hair]. He's just a star in the making.
