It does make you wonder, but we'll never know. There are a whole bunch of things Mendoza could have done or not done to keep himself off the field. From what I hear, Bo does seem to be pretty good about playing the guys who work hard in practice and do the things they are asked to do. Based on that, it seems like he must not have been getting it done at practice. I think Bo would have just kicked him off the team if it was an off-the-field issue but I guess its possible he could have just been in the doghouse for the last two years.
