The Denver Broncos made several additions in the 2015 NFL draft. They started the draft out with a bang, moving up in the first round for pass-rusher Shane Ray. The following rounds saw them acquire talent for both sides of the ball. Some could be starters as rookies; some could be valuable reserve players, while others could be considered developmental players who need more time before they contribute on Sundays.

With the 90-man roster pretty much filled out, the Broncos will go through rookie minicamp, veteran minicamp and offseason training activities (aka OTAs) over the next several weeks.

These rookies are going to try to turn heads with every single rep they receive during that time. For certain veterans, these reps are also critical as the team approaches training camp.

Every single drill is an opportunity for players on the roster bubble to prove what they can do. With a talented group of rookies coming in, a few veterans need to impress in order to keep their spot on the depth chart.

Here are five Broncos veterans who are now on the roster bubble following the draft.
