Sorry, but 8 receptions in 3 years brings ZERO to the receiving table.
Once you take out the receiving from the FB title, all that is left is blocking.
So who has more experience in blocking a starting lineman in college or a starting FB in college?
The easy answer is that a starting lineman in college has many more chances to block than a starting fullback in college.
Who has more chances of blocking in the pros?
This one becomes a little more interesting because a backup lineman only will block when someone in front of him is injured while a starting FB is used rarely.
I honestly would rather use the spot for another TE, OLB or CB. However, if the Bears decide that they need someone to be the battering ram in front of the HB, don´t be stuck with the notion that a Clutts or Burton would be better than someone who has played as an offensive lineman all his life, be it Grasu or any athletic lineman the Bears can find.
Quick question: What will happen the next time that Mike Burton catches a football in an NFL game?
Answer: The career receptions for Tyler Clutts + the career receptions for Mike Burton will equal 20 receptions, not each ... total.
