Well, there's a subject - Jonathan 
Object, I THINK would be playing football. 

Isn't that all you need for a complete sentence? 
Sorry if I'm a little rusty on this - haven't studied it in a while.

I'm pretty sure, that's what I think also so should I put complete sentence?

It seems like a perfectly complete sentence to me. I can't imagine where it would be a fragment, much less a run-on.

Yeah I guess so this is the definition of a complete sentence anyways: A complete sentence is a group of words related by meaning, which: Starts with a capital letter and ends with a period (exclamation or question marks); Has a subject and a verb predicate (which should agree with each other in number); Has a complete thought.

It fits along those lines right?

In my opinion, absolutely.

Ok well thanks for your help!

The verb tense agrees, it's a complete and finished thought, it has a subject - yes.
