Tobias was way over hyped by BD. He isn't ready, and simply might not be an alpha. He's very slight of build still and has shown a lack of desire tracking and fighting for the ball. Coaches can be blamed for lack of skill, but desire is on the player.
Again, when you have the luxury of experienced guys on your team you can teach freshmen to do one or two things really well ..and the can focus on doing those in games and look great...that's what other teams do.
Notre Dame, due to depth and injuries is depending on freshmen to come in a know the entire route tree at a high level and that is simply not a path to success.
Having said that first year guys Tyree, faison, and Flores have played very well. Consider Tyree was supposed to be splitting his reps, faison was a walkon and Flores was behind fake breakout merriweather and it's tough to complain about stuckey. Consider thomas' level of play pre injury as well as even greathouse and it appears stuckey is actually doing well
