The Jays haven't really had a great third baseman before. The question wouldn't be worth asking at many other positions, but for third base the possibilities are:
- Garth Iorg
- Rance Mulliniks
- Kelly Gruber
- Ed Sprague
- Tony Fernandez
- Tony Batista
- Scott Rolen
- Edwin Encarnacion
- Brett Lawrie
The only real competitors are Kelly Gruber and Scott Rolen:
Kelly Gruber had 5.8 WAR in 1988 and averaged 4.9 WAR in the 1988-1990 time period. He didn't do a whole lot in his other seasons though.
Scott Rolen has HOF stats but was past his prime when he joined the Jays. He still had a very good 203 games between 2008/2009 with 6.2 total WAR and a WAR/150 of 4.6
Brett Lawrie has 5.4 WAR in 124 games for a WAR/150 of 6.5
So the question is, if not Brett Lawrie, which former Jay would you rather have playing 3B right now?
