Here are five things that stood out on Tuesday:
1. The NFL descends upon college football's finest
More than 1,000 NFL personnel staff members, scouts and decision-makers began the evaluation process of the 110 players competing at the Senior Bowl on Tuesday.
With this many of the most important people in the NFL all in one place, the entire city of Mobile revolves around the Senior Bowl this week.
This is the time for these players to show teams what they can do and the NFL is once again well represented here in Mobile.
The players received their official measurements this morning at the Senior Bowl National Scouting Weigh-In and those results can be found here.
2. Weather couldn't be more perfect
While it's not breaking news, the weather on Tuesday was perfect in Mobile for these players to show what they could do during the two respective practices.
It could be taken for granted, but the importance of this week has been well documented and the fact that the weather is cooperating is music to the ears of those who need this week to build their football teams heading into the 2015 season.
3. Size not an issue for the North team
Between Florida's Trenton Brown, who measured in at 6-foot-8-and-a-half, 376 pounds, and Washington defensive lineman Danny Shelton, who stood at 6-foot-1-and-three-fourths, 343 pounds, size isn't an issue for the North team.
Shelton, who already came into Tuesday's practices as one of the most talked about players coming into the Senior Bowl, did nothing to shy away from the attention he's been getting.
He showed nice athleticism in positional drills for a player of his size and he has a good opportunity this week to earn the praises he's been getting since his season at Washington ended.

4. K-State's Tyler Lockett stands out for the South team
After dominating the record books at Kansas State, Tyler Lockett has already made an impression at the Senior Bowl as well.
The 5-foot-9, 181-pound receiver made a fantastic play deep down the field at Fairhope Stadium in the afternoon practice for the South team, beating former Auburn quarterback turned defensive back Nick Marshall in the process.
Lockett has said he's going to be primarily working the slot this week, which seems to be working well for him already as he made a few plays on underneath routes as well.
5. Chiefs scouting department sits together
While they all watch different things, the Chiefs personnel staff takes its usual seat in the stands of Ladd Peebles Stadium together.
John Dorsey can be found roaming around and watching different positional groups, but for the most part, they sit together and work through their evaluations.
