With the NFL cancelling its annual pre-draft scouting combine in Indianapolis, teams' pro days for their players have taken on more importance than ever. All players official pre-draft workouts and measurements in front of NFL scouts are being conducted on the respective schools' campuses.

After its first pro day on March 23, Alabama is hosting a second pro day for its athletes, and there has been no shortage of headlines produced in the lead up to it.

Starting with Mac Jones: after the San Francisco 49ers traded up to the third pick last week, Mac Jones rumors immediately began to fly. Jones has been compared by some to quarterbacks 49ers head coach Kyle Shanahan has had success with in the past such as Matt Ryan and Jimmy Garoppolo.

Those rumors grew even louder yesterday when it was announced that Shanahan and GM John Lynch would opt to skip Justin Fields' first pro day at Ohio State in favor of attending the Alabama pro day Tuesday to see Mac Jones throw. While this very well could mean nothing, it is interesting nonetheless.

As for some other Alabama stars, the picture is even less clear. According to Mac Jones, while he has a script prepared for Jaylen Waddle and Devonta Smith to run routes, both talented receivers are still undecided as to whether or not they will be participating.

Waddle, who returned for the national championship from a broken ankle suffered in October against Tennessee, is a bigger question mark than Smith due to his health. However, Waddle has stated several weeks ago to NFL Network that he would be running his 40 yard dash, which probably indicates that he is feeling 100%.

Najee Harris, who famously drove nine hours to be at the first pro day even though he was not participating, will be participating in the second event, at least according to Mac Jones. Harris will likely go through his positional workout and in all likelihood, catch some passes from Jones as well. He will not run a 40-yard dash, unfortunately.

On the defensive side of things, we know Dylan Moses will not be going through any drills after he announced that he played through the 2020 season with a torn meniscus. Moses will conduct interviews with teams only.

With just a few weeks until the NFL Draft, Tuesday's pro day will serve as one final chance for Alabama players to make an impact on NFL scouts. The pressure will certainly be on, and it will be up to each individual player to leave a final positive impression.
