A major decision for every top quarterback prospect heading into the combine is whether or not to take part in passing drills. These drills typically put the quarterback at a disadvantage as they are required to make those all over the field with receivers whom they might have never met before. It might sound simple to most people, but timing and knowing your receivers is vital to a quarterback’s success.

One of the most recognizable names in this year’s draft, Johnny Manziel, made his intentions known on Friday thru his agent when he’ll be throwing for scouts.

This means that Manziel will also not be throwing at Texas A&M’s pro day early in March. This is typical for most top quarterback prospects.

UCF’s Blake Bortles has a different approach to this year’s combine.

While I do not believe it to be a detriment to a player if he decides not to throw at the combine, I do believe a decision for a top quarterback prospect to in fact throw at the combine shows that player’s competitive nature.

Bortles is in a battle with Manziel and Teddy Bridgewater to be this year’s top quarterback selected. In my 1st mock draft of 2014, I have Bortles being selected by the Minnesota Vikings with the 8th overall selection.

If the Bucs are not sold on Mike Glennon as their quarterback for the foreseeable future, you can guarantee that GM Jason Licht and head coach Lovie Smith will have a close eye on Bortles and the other top quarterbacks in this draft during this weekend’s combine in Indianapolis.
