The logline is clunky but the set up seems quite different from the norm for a football movie. So methinks there is potential here. The protagonist, however, is hard to sympathise with as stated - since he seems to be on the cold side. But this point can be easily fixed by emphasising his desire to resuscitate his low profile town. In addition, one positive thing about the protagonist is that he does not seem to be the straightforward former-player-macho-bonehead stereotype.
So here's a logline suggestion: "To resurrect the flagging fortunes of his beloved home town, Sonny daringly drives his football club to buy up the number one pick of the NFL Draft. But the pick is hotly contested property and the cost on Sonny's personal life will be high."
