All recruits have questions regarding their skills, even 5-star prospects. However, some have fewer than others, as they have what is commonly called a "low floor." These recruits possess the skills to be solid players even if they do not reach their full potential.
Some college coaches prefer signing prospects with high ceilings, because if the player maxes out his talent, he projects to be a better player than the recruit with a lower floor. Yet, recruits with lower floors are the safer bets to have success in college.
When examining the 2014 class, a pair of quarterbacks have potential worst-case scenarios that aren't bad. Another prospect is so athletic that he essentially will have multiple chances before he is deemed a bust. And a defensive end recruit's talent screams "what you see is what you get" on tape.
