A constant issue I read in articles in print and online is the supposed "panic" we're supposed to have regarding the center position battle. This is my argument in favor of not panicking.
First off, it's August 14th. If you're worried about something like this, get a hobby. Let's talk again on September 1st when we have to data to analyze.
Second, there are certainly untold examples of walk-ons pushing starters that are harbingers of doom (think back to 2008-10). Likewise, there are plenty of situations where walk-ons (not preferred walk-ons like Glasgow) turn into NFL players. The "walk-on challenging the scholarship player" is not a storyline worth worrying about.
Third, your reason not to worry proves itself when you look at this particular position battle. When Glasgow entered the recruiting process, there is a specific reason he only garnered preferred walk-on offers from Ohio State, Michigan, MSU, Minnesota and NIU (his parents were team doctors at NIU and Kill offered him in the latter two places as a PWO, and maybe the question should be why didn't other Big Ten schools offer this kid once the big boys showed PWO interest?). He only played one year of high school football. He was all-state that year. However, he had previously played basketball (I could insert talk about footwork here) and switched over late.
SO what do we know? He's a great athlete, he started playing late, the programs offering him probably were playing poker, hoping to get a guy into a program without committing a scholarship to him. He's now in his 3rd year in the program (same as Miller), he's played in one game fewer than Miller (5 v. 6), and is sufficiently developed and ready to play.
And don't forget one more thing. He was on scholarship last year and I suspect this year as well. Evidently, this guy is proving his worth.
So my message to you all - get rid of the "walk-on" talk, and don't worry. If Glasgow is playing, choose to view it as him developing in his third year of the program, and beating out a solid alternative, and pretend this is what Jordan Kovacs's career development would've looked like had the program had solid (hell, any) roster alternatives in 2009 and 2010.
I'm now going to watch a replay of the 73-yard rushing TD Berkley Edwards pulled off in last Saturday's scrimmage at TCF Bank Stadium.
