Tim Tebow is ready for the shots, both on the football field and in the locker room. The two-time national champion from Florida practiced with other rookies Friday in advance of the start of the Denver Broncos' training camp and said he couldn't wait for the hard hits. Tebow, the 25th pick in the NFL draft, is fresh off putting his signature on two contracts, one of them a five-year deal to play for the Broncos and the other a multiyear deal to serve as a pitchman for Jockey underwear. http://sports.espn.go.com/nfl/train...ss&source=twitter&ex_cid=Twitter_espn_5424493
