The 21-year-old slipped down to pick No. 41 in the 2011 NAB AFL Draft and debuted for Adelaide last year.
Speaking to fans via the AFL's Twitter account, Sanderson said he thought Grigg was set for a big year in 2014.
Grigg played five of the Crows' last six matches in 2013 and averaged an impressive 18 disposals, four inside-50s and five tackles in his final three games.
He also showed he could have an impact on the scoreboard, kicking six goals.
Grigg was also a part of Norwood's SANFL Grand Final winning team last year.

— AFL (@AFL) February 25, 2014.@amykins83 Yes, he's had a really solid pre-season and will provide great back-up for Sauce #askthecoach
— AFL (@AFL) February 25, 2014.@JRickard1991 Yes, he'll play plenty of AFL football this year and for us long term. #askthecoach
— AFL (@AFL) February 25, 2014.@45bombadil Haha. The reason I shaved my head is in support for Dean Bailey while he's fighting his cancer. #askthecoach
— AFL (@AFL) February 25, 2014.@James__McRae We'll only train their twice before we first play, but we're looking to quickly make it a great new home ground for us.
— AFL (@AFL) February 25, 2014.@Ricobird1 Wrighty will play a variety of roles for us, but has a had a great summer, and looks set for a big season. #askthecoach
— AFL (@AFL) February 25, 2014.@Slaternator Definitely. He's a player who's had injuries himself earlier in his career, but if things go to plan, will have a good season.
— AFL (@AFL) February 25, 2014.@AFCReddit Definitely a chance, but the midfield is such a competitive area for us. Hopefully they play together for 10 years plus.
— AFL (@AFL) February 25, 2014.@AFLDreamers Sam's a really important player for us. Didn't play at all for us last year, but hopefully can recapture his 2012 form.
— AFL (@AFL) February 25, 2014.@BILLZ_17 Ellis-Yolmen, Matt Crouch, Grigg, Cameron, Hartigan, Johnston, Kerridge, Lyons are probably the main ones #askthecoach
— AFL (@AFL) February 25, 2014.@cgsteer @Adelaide_FC Yes, he's had a few injury setbacks, but is definitely in the frame for round one. #askthecoach
— AFL (@AFL) February 25, 2014.@captaincaple McKernan, Jenkins, Graham, Osborn are the next four #askthecoach
— AFL (@AFL) February 25, 2014Yes, plenty of Gatorade! RT @thomasdoak: .@AFL Will the players be able to drink during the season this year? #askthecoach
— AFL (@AFL) February 25, 2014.@deanbarber I think Mitch Grigg is set for a big year. #askthecoach
— AFL (@AFL) February 25, 2014.@irishlfc05 Carlton's defence didn't give us the corridor last night, which led us along the boundary too often #askthecoach
— AFL (@AFL) February 25, 2014Big thanks to all the fans for the questions. Looking forward to a great season. Go Crows! - Sando #askthecoach
