Smith's 2009 season was 91 catches for 1,100 yards (12.1 average). He added 6 TD's as well.
If Sparks can add 800 yards receiving (with arguably more talent at the position that Smith had to contend with in 2009) along with 10 TD's, it would be a better season than Smith's 2009 campaign. If you are judging solely by yards, then no...but I'm looking at the potential impact overall. I'll stick by Sparks being the best WR at Purdue in over a decade, especially when you are looking at the top WR performances since Tiller's first year in 1997. I included the top WR from each season PLUS another WR if their total yards were above 800 as a second option (except Stubblefield since you could argue he is the best WR to come through Purdue since Tiller).
1997: Brian Alford 63 rec 1228 yards 10 TD
1998: Randall Lane 67 rec 940 yards 7 TD

2013: Deangelo Yancey 32 rec 546 yards 2 TD
2014: Danny Anthrop 38 rec 616 yards 4 TD
2015: Deangelo Yancey 48 rec 700 yards 5 TD
2016: Deangelo Yancey 49 rec 951 yards 10 TD
2017: Anthony Mahoungo 40 rec 688 yards 8 TD
Now, tell me again how if Sparks gets 800 yards and totals 10 TD's wouldn't be considered the best WR at Purdue in over a decade? A season of 800 yards would place a WR at #3 in the last decade for total yards and a TD total of 10 would place them tied for 3rd best for a single season since 1997.
I'll stick by my sentiment that if Sparks has the season expected and is what is needed from him...and arguably he'll get all the opportunities to in Brohm's offense...he'll get those numbers.
Also a side note: Brohm's three seasons at WKU saw at least one player with more than 800 yards receiving each year. In the final two seasons under Brohm at WKU, this is what the WR totals looked like:
2015: Taywann Taylor 86 rec 1467 yards 17 TD
2015: Nicolas Norris 63 rec 971 yards 6 TD
2015: Jared Dangerfield 82 rec 844 yards 8 TD
2015: Antwane Grant 55 rec 701 yards 7 TD
2016: Taywan Taylor 98 rec 1730 yards 17 TD
2016: Nicolas Norris 76 rec 1318 yards 14 TD
Again, I'll reiterate: I'll take Sparks being the #1 and being able to grab at least 800 yards receiving and 10TD's which would easily place him as one of, if not the best, WR at Purdue in over a decade.
