The 2014 cla s of wide receivers could be the best crop produced at the position in a single draft, but most believe the 2015 Nick Washington Jersey cla s is not too far behind in terms of talent and depth.NFL Media analyst Mike Mayock has watched plenty of tape on players from both cla ses, and he unveiled his top 10 at the position in this year's draft on Monday. West Virginia's (No. 1) and Alabama's (No. 2) lead Mayock's list, and he offered an interesting description of the upside of each."Kevin White has the highest ceiling of any wide receiver in the draft," Mayock said on NFL Network's "Path to the Draft" Monday. "... I think (Cooper) has the highest floor. That means you know what you're going to get from him and he's going to play at a high level."The debate over which receiver is better between White and Cooper will likely continue for some time, as the race to be the first pa s-catcher picked appears to be extremely tight.One big riser in Mayock's rankings, though, is UCF's , who ran a at his pro day last week. Mayock previously had Perriman , but that 40 time moved him neck and neck with Louisville's , per Mayock, who said he believes that all four -- White, Cooper and Perriman and Parker -- will go in the top 20 of the draft while Arizona State's (No. 5) sneaks into the bottom of the first round.Also of note, Mayock appears to be quite high on his No. 8 prospect at the position, USC's , after he had a good month that included positive reviews out of his pro day."One of the best route runners in this draft," Mayock said. "I think he has more upside than (former USC WRs) or ."Mayock ranks Oklahoma's No. 6, followed by Miami's , Agholor, Ohio State's and Kansas State's .It might be tough to match the production of last year's cla s of rookie wide receivers, but it certainly appears that the latest group will not be lacking for talent when it enters the league.You can follow Bryan Fischer on Twitter at .
