Michael Sam is excited about the next phase of his NFL career

Now it starts to get intense for Michael Sam and the rest of the St. Louis Rams rookies.

The first openly gay player drafted in the NFL is enthusiastic about the challenge.

Twice on Tuesday, he mentioned how much fun he was having.

Sam said he hopes the attention is less about his sexual orientation, but added his focus has to be on making the team.

He said he's in the best shape of his life, dropping 13 pounds in the month since the last OTA workout.

A little more than two dozen newcomers participated indoors.

Sam thought it felt much like another OTA, but noted no one had pads on yet.

On Day 1 his biggest concern was mastering nuances of playing right end.

He was the SEC co-defensive player of the year at Missouri rushing from the left side.
