Earlier Monday, we looked at the contract situations of tight end Vernon Davis and guard Alex Boone. Now, we take a look at some of the other storylines that developed while I was on vacation:• Aldon Smith pleads no contest to three felony weapons charges and two misdemeanor counts of driving under the influence.My thoughts: Smith is set to be sentenced July 25. He could face jail time. He could also face an NFL suspension. Smith's future is very much up in the air.
